I'm seeing IAPError(code: storekit_no_response, source: app_store, message: "StoreKit: Failed to get response from platform.") when calling queryProductDetails() (via Flutter's in_app_purchase/in_app_purchase_storekit plugin) for all 6 of my app's In-App Purchase products. This happens consistently on a real device (iOS 18.7.9), including after a full device restart. I've followed the entire TN3186 checklist: Paid Apps Agreement: Active Banking: Active Tax Forms: Active Bundle ID matches App Store Connect and Certificates/Identifiers/Profiles In-App Purchase capability is enabled on the App ID All 6 product identifiers match exactly and are attached to the app version under review Pricing is set for all territories on all products None of this resolves the error. This also caused an App Store review rejection citing "In-app purchase products... could not be found in the submitted binary" for the same reason. Bundle ID: com.playadda.playadda Product IDs affected: gems_pack_100, gems_pack_500, gems_pack_1200, premium_monthly, battle_pass_s1, starter_pack Has anyone found a resolution to this specific error beyond the standard TN3186 checklist?

Transaction.finish() doesn't clear a transaction on iOS 27 beta 5 — worked correctly through beta 4 — every repeat purchase after the first replays the same transaction with no confirmation sheet and no charge. StoreKit.Transaction.finish() does not clear a transaction on iOS 27 beta 5. The transaction remains in Transaction.unfinished indefinitely, and every subsequent Product.purchase() call for that product returns the same stale transaction instead of starting a new purchase — with no confirmation sheet, no charge, and no way for the app to tell it apart from a genuine purchase. Because the replayed result is .success carrying a VerificationResult that verifies normally, an app has no supported signal that nothing was bought. The only distinguishing traits are that the id and purchaseDate are unchanged and the call returns in ~10ms instead of making a server round-trip. Consequence: a consumable product can be purchased exactly once per device. Every later attempt silently no-ops while appearing to succeed. Steps to Reproduce On a device running iOS 27 beta 5, sign in to a newly created Sandbox Apple Account (Settings → Apps → App Store → Sandbox Account) with no prior purchase history. Install and launch a development build of an app offering a consumable IAP. Confirm Transaction.unfinished is empty. Purchase the consumable. The confirmation sheet appears and the purchase completes normally. await transaction.finish() on the returned transaction. Enumerate Transaction.unfinished again. Purchase the same consumable a second time. Expected Results Step 6: Transaction.unfinished is empty — the transaction was finished. Step 7: a confirmation sheet appears and a new transaction is created, with a new id and a current purchaseDate. Actual Results Step 6: the just-finished transaction is still listed in Transaction.unfinished. Step 7: no confirmation sheet appears. purchase() returns .success in ~0.01s carrying the same transaction — identical id and identical purchaseDate — and nothing is charged. This repeats indefinitely. Re-fetching the transaction from Transaction.unfinished and calling finish() on that instance does not clear it either, so there is no app-side way to drain the queue. Diagnostic Log Virgin sandbox account, empty queue, three consecutive taps on one product: unfinished before tip.small: [] purchase() returned after 18.10s tip.small: id=2000001221113013 purchaseDate=2026-08-13 22:36:26 +0000 --- await transaction.finish() --- unfinished after finishing 2000001221113013: [small#2000001221113013] unfinished before tip.small: [small#2000001221113013] purchase() returned after 0.01s tip.small: id=2000001221113013 purchaseDate=2026-08-13 22:36:26 +0000 unfinished before tip.small: [small#2000001221113013] purchase() returned after 0.01s tip.small: id=2000001221113013 purchaseDate=2026-08-13 22:36:26 +0000 The first call is a genuine purchase (18s round-trip, sheet shown). The transaction survives its own finish(). Calls two and three are replays of it. Notes Not reproducible against a local .storekit configuration in the Simulator, which always presents the confirmation sheet. Requires Apple's sandbox. Also reproduces on a TestFlight build billed to a real Apple ID, where it is worse: TestFlight purchase history cannot be reset, so the affected products stay permanently stuck for that account. It survives deleting and reinstalling the app, and a device reboot. Possibly the same underlying issue as the unanswered report at https://developer.apple.com/forums/thread/808648 (iOS 26/18, Nov 2025). Configuration Device: iPhone 16 Pro Max OS: iOS 27 beta 5 Products: consumable in-app purchases API: StoreKit 2 (Product.purchase(), Transaction.finish(), Transaction.unfinished)

I am experiencing a StoreKit issue on iOS 27 Beta with eFootball™ 11.0.0 (jp.konami.pesactionmobile). After an in-app purchase, the app becomes stuck on an infinite loading screen during login. If I manage to log in, the in-game Shop also remains stuck loading. I investigated the issue using macOS Console and found that StoreKit repeatedly attempts to finish the same production transaction every approximately 2–3 seconds. The relevant logs are: Starting request FinishTransactionRequest(...) Failed to encode request parameters NSCocoaErrorDomain Code=3840 Error finishing transaction: StoreKitServiceError StoreKitInternalError.requestEncodeFailed The same transaction is repeatedly passed to FinishTransactionRequest, but the finish operation never succeeds. What I have confirmed The purchase itself was confirmed by Apple Support as successfully completed. The transaction is a Production transaction with the JPN storefront. Reinstalling eFootball does not resolve the issue. Restarting the iPhone does not resolve the issue. Signing out and back into "Media & Purchases" with the affected Apple Account does not resolve the issue. Network requests from the app itself are succeeding with HTTP 200 responses. The issue occurs when StoreKit attempts to finish the transaction. Most importantly, if I sign out of the affected Apple Account under Media & Purchases and sign in with a different Apple Account on the same iPhone, eFootball immediately works normally again — both login and the Shop load successfully. If I switch back to the original Apple Account, the issue returns. Steps to reproduce Use the affected Apple Account for Media & Purchases. Launch eFootball. Attempt to log in. The app remains stuck loading. Observe Console logs from storekitd. The same transaction repeatedly triggers FinishTransactionRequest. Each attempt fails with StoreKitInternalError.requestEncodeFailed. Expected behavior StoreKit should successfully finish the completed transaction, remove it from the unfinished transaction queue, and allow the app to continue normally. Actual behavior FinishTransactionRequest repeatedly fails with requestEncodeFailed, causing the same transaction to be processed indefinitely and preventing normal use of the app. Has anyone encountered the same behavior on iOS 27 Beta? Is this a known StoreKit issue, or is there any way to safely clear/finish the affected production transaction without restoring the device to the current public iOS release?

Hi, Overview In my project I am using a .storekit StoreKit configuration file that is synced. I have only non-consumable products Problem When I loop through Transaction.currentEntitlements after verification the properties such as transaction.productType are all NULL. Note I have called .finish on the transaction after the following: Processing Transaction.updates Processing purchasing a new product Environment: Xcode 27 Beta 5 iOS 26.6 Questions How can I resolve this? Am I missing something? Should I be using Transaction.latest(for:) instead of Transaction.currentEntitlements?

Summary: We gate premium access on the renewal status returned by Product.SubscriptionInfo.Status.all, following the pattern in your Implementing a store in your app using the StoreKit API sample (CustomerEntitlements.checkCurrentStatuses()). In production we are seeing a subset of users whose Status.all yields zero statuses, even though they hold an active subscription with a future expiration date (according to our own persisted state). This causes us to incorrectly treat them as unsubscribed. How we read status: func currentSubscriptionStatuses() async -> [SubscriptionStatusInfo] { await Product.SubscriptionInfo.Status.all .collect() .flatMap(.1) .compactMap(SubscriptionStatusInfo.init(skStatus:)) } The compactMap only drops entries failing case .verified. In the affected cases Status.all itself emits no (groupID, statuses) pairs at all - the sequence is empty, not filtered. Affected population: Previously had an active paid subscription (our own persisted state shows pro with an expiry date in the future). Not new installs. Questions: Under what conditions can Product.SubscriptionInfo.Status.all return an empty sequence for an Apple Account that currently holds an active auto-renewable subscription (e.g. not signed into the App Store, StoreKit not yet initialized at launch, offline, renewal in flight, Family Sharing)? Is an empty result from Status.all ever authoritative ("no subscription"), or must it always be treated as inconclusive and never used to revoke access? Is there a recommended way to distinguish "no subscription for this account" from "status temporarily unavailable" (e.g. a signal for no signed-in App Store account, or a readiness/error path)? Does Status.all guarantee it reflects a signed-in account context, and what is the expected behavior when the device has no active App Store account at call time?

FB: https://feedbackassistant.apple.com/feedback/22556883 We're seeing a small number of production users where both Transaction.currentEntitlements and Transaction.all return zero transactions for a valid, active, non-refunded non-consumable IAP. This makes it impossible to restore the purchase via any StoreKit 2 API. Environment: Xcode 26.4 (Build 17E192) iOS 26.4.1 Direct call to SK2 Transactions.all & Flutter in_app_purchase package v3.2.3 (uses SK2 on iOS 15+) Non-consumable IAP (one-time purchase) What we observe: AppStore.sync() triggers but the purchase stream returns 0 transactions Transaction.all returns empty Transaction.currentEntitlements also returns empty User is confirmed on the correct Apple ID Issue reproduces on both iPhone and Mac for the same Apple ID Issue appears to have started recently for users who previously had no problems Debug log from affected production user: [2026-04-20T08:50:10.744115Z] init: iapAvailable=true [2026-04-20T08:50:10.744566Z] init: isPremium=false [2026-04-20T08:50:10.744567Z] init: triggering silent restorePurchases [2026-04-20T08:50:45.974566Z] restore: started [2026-04-20T08:50:45.986848Z] restore: sk2Transactions count=0 [2026-04-20T08:50:45.993004Z] restore: sk2Direct isVerified=false active=null [2026-04-20T08:50:45.993011Z] restore: sk2Direct inconclusive — falling back to standard restore [2026-04-20T08:51:16.000851Z] restore: timed out after 30s — fallback isPremium=false [2026-04-20T08:51:16.000910Z] restore: completed — succeeded=false foundPurchase=false Unable to reproduce in sandbox — Transaction.all works correctly there. Appears specific to production for a small subset of users. Has anyone else seen this?

Product: Auto-renewable annual subscription Environment: Production iOS version: 26.6 StoreKit version: StoreKit 2 I have an active subscription that shows correctly in the App Store app, but neither Transaction.currentEntitlements nor Product.SubscriptionInfo.Status (via subscription.status) return any record of it — both come back empty. What I've checked: Transaction.currentEntitlements — iterated fully, zero transactions found for this product ID Product.SubscriptionInfo.Status — checked independently as a second signal, also returns no active status for this product AppStore.sync() — called before checking entitlements, completes successfully, does not resolve the issue Settings → [Apple ID] → Subscriptions on-device — does not show this subscription "Restore Purchases" in-app — consistently reports nothing found Impact: Since my app gates access behind an active entitlement check, this means the user is stuck on the paywall screen indefinitely, despite having a valid, active, paid subscription. There's no client-side workaround, since every available StoreKit 2 API reports no entitlement exists. Code pattern (simplified): swift for await result in Transaction.currentEntitlements { if case .verified(let transaction) = result, transaction.productID == productID { // never reached for this product } } if let subscription = product.subscription { let statuses = try await subscription.status // statuses is empty / doesn't reflect the active subscription } This looks consistent with the pattern reported in thread 823454, where currentEntitlements and Transaction.all return empty for valid, non-refunded purchases in production for a small number of users. In my case, this is affecting a currently active subscription — not a refunded or expired one — and is reproducible on this account across multiple app builds. Has anyone found a reliable workaround, or is this being tracked by Apple as an active known issue beyond the fix already applied for the non-Gregorian calendar case (which doesn't apply here)?

Summary: The "In-App Purchases or Subscriptions" selection section does not appear on my app version page, so I cannot attach my first In-App Purchase to my build. This has caused four consecutive Guideline 2.1(b) rejections. Setup: App: Qmetra IQ (Apple ID 6791254506, Bundle ID com.vibecode.qmetraiq.londa9) First app release, never published App version 1.0, current build 1.0.1 (2) Non-consumable IAP: com.vibecode.qmetraiq.londa9.results (Apple ID 6792799431) IAP status: Ready to Submit App Review screenshot for the IAP: uploaded (1242×2688) Paid Apps Agreement signed, banking and tax complete, no open items under Business What I see: On the version page, the "In-App Purchases or Subscriptions" heading exists, but contains only an informational message ("...add an app version to your submission so the items are reviewed together..."). There is no button, link, checkbox, or "+" to select the IAP. The submission draft panel contains only the app version, with no way to add the IAP. Opening the draft from the IAP page shows only the IAP, with the warning "Cannot be submitted for review — add an app version for the selected platform", and the "Submit for Review" button greyed out. What I have tried: Removed the previous rejected submission from review, then rechecked the version page — section still absent Assigned a fresh build (1.0.1 build 2) and saved Re-saved the IAP metadata Resubmitted the app version alone — rejected again under 2.1(b) Replied in the review thread twice — no resolution Rejection reason each time: "one or more of the In-App Purchase products have not been submitted for review." Could an Apple staff member please forward this to App Store Connect Support or engineering so the In-App Purchase can be moved to In Review manually? Several older threads describing this exact bug were only resolved that way. Happy to share more details privately if needed. Thank you.

Hi Apple Developer Community, I’m preparing an iOS app called Titech for App Review. The app is intended for clinic/business users and provides preliminary AI-generated cosmetic analysis and preview guidance based on user-submitted face photos. The app is not intended to provide medical advice, diagnosis, or treatment decisions, and users are told to consult qualified experts before acting on any recommendation. We have received multiple App Review rejections and I would appreciate guidance on whether our current approach is aligned with Apple’s expectations. Current issues raised by App Review: Guideline 2.1 - Information Needed Apple asked for more information about how the app uses face data, including: What face data is collected How it is used, stored, retained, deleted, and shared Whether it is shared with third parties Where this is explained in the privacy policy Exact privacy policy text about face data We updated the app and privacy policy to explain that: Users voluntarily upload front, left-side, and right-side face photos Photos may be sent to our backend and processed by OpenAI through the OpenAI API Face ID/fingerprint data is not collected Uploaded face photos and generated preview images are deleted after the active session ends The app does not sell face data or share it with advertisers/data brokers Guideline 2.1(b) - Information Needed Apple asked about the business model and whether users access paid content. Our app does not currently include paid digital content, subscriptions, credits, or in-app purchases. Access is controlled by a registration code for clinic/business users and App Review only. Guideline 2.3.3 - Accurate Metadata Apple said the screenshots did not show the current version of the app in use. We replaced the screenshots with updated iPhone and iPad screenshots showing: Clinic access Consent and face-data disclosure Photo capture AI-generated analysis Recommendations Side effects page Generated preview flow My questions: For apps using user-submitted face photos with a third-party AI API, is it enough to clearly disclose OpenAI processing in the consent screen and privacy policy, or should this also be repeated elsewhere in the app flow? For face photos that are deleted after the active session ends, what wording does Apple generally expect around retention and deletion? Since the app is clinic/business access only and does not sell digital content, is a registration code acceptable if we clearly explain that it is not a paid digital unlock? Are there any additional App Review notes or privacy policy sections that developers usually include for apps involving face photos and AI-generated preliminary recommendations? For metadata, should the screenshots avoid login/consent screens entirely, or is it acceptable to include them as long as most screenshots show core app functionality? Any advice from developers who have passed review with apps involving user-uploaded face photos, AI analysis, or cosmetic/health-adjacent recommendations would be very helpful. Thank you.

Hi, I am unable to sign into the sandbox account on the simulator. Settings > Developer > Sandbox Apple Account > Sign in Xcode: 26.6 (17F113) Xcode Simulator: 16.0 (1063.4) I have even tried on Device Hub on Xcode 27. I vaguely remember being able to sign into the simulator using Questions: Is anyone able to sign into Sandbox account on the simulator / device hub? Is there any workaround? Is this a known issue?

iOS 26.4系统上，我们发现三个问题： 1.调用了finishTransaction接口，但是在App重新启动后，[SKPaymentQueue defaultQueue].transactions仍然会有这笔订单。 2.支付完成后，[[NSBundle mainBundle] appStoreReceiptURL]]，拿到的票据解析出来里面的商品是空的，需要延迟2秒钟左右在调用[[NSBundle mainBundle] appStoreReceiptURL]]才能获取有效票据。 3.支付完成后，如果用户没有点击最后弹出的确认弹框，等待5秒钟，系统会自己回调 - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions; 代理方法。正常应该是用户点击了最后弹出的确认弹框，在回调- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions;方法。 我们在苹果开发者论坛上面找到其他开发者反馈的类似问题，链接如下： https://developer.apple.com/forums/thread/817700 https://developer.apple.com/forums/thread/792437?answerId=849557022#849557022 https://developer.apple.com/forums/thread/817834 https://developer.apple.com/forums/thread/817706 https://developer.apple.com/forums/thread/818586 我们有大量用户升级到了26.4系统，这对于我们造成了巨大的困扰，我们需要你们的帮助，感谢！

TL;DR: Does iOS automatically receive App Store transaction updates in the background when internet connection is available so the backing storage state of Transaction.currentEntitlements gets synced even when my app is not running? Or does iOS update Transaction.currentEntitlements only when my app is running? The long version: Imagine the following situation: A user has purchased a non-consumable IAP in my app and is granted the locked premium content. The IAP transaction is now present in Transaction.currentEntitlements (it's also cached locally). The user blocks internet access every time before my app gets opened (either enables the Airplane mode and/or disconnects from the Wi-Fi before launching my app). So from this point on, my app never gets a chance to connect to the internet. The user gets refunded for the IAP. The user uses their iPhone to browse the internet via Safari, checks emails, etc. Then, before launching my app, the user blocks internet access. My app gets is launched (without internet access) and reads entitlements from Transaction.currentEntitlements. The question is: does the StoreKit service know that the IAP has been refunded? Did iOS update the local cached storage of Transaction.currentEntitlements while the user was connected to the internet in step 4? Or will Transaction.currentEntitlements contain the old state from step 1 so the app won't know about the refund and the user will be able to use my app's premium content which has been refunded by now? Is the behavior the same for auto-renewable subscriptions as it is for non-consumable IAPs?

Hello all! Have open source iOS application. Is it possible to use In-App purchasing (subscription or any other) for donations? Will it be against any kind of Apple rules? The application have no paid content. Just only donations needed. Will it be passing publications checking? This question isn't about using crowd funding or any other kind of platforms. This question about Apple rules exactly.

I have two subscription in the same group and the same level 1. One is a monthly one and the other a yearly one. I also have an IAP for Lifetime Unlock. When my app requests for these it only loads Monthly. Debugging reveals that the ASC doesn't return the yearly subscription and the lifetime IAP. When I added a StoreKit config to the app, it correctly show the Yearly subscription as well and the view loads it appropriately. But the storekit config doesn't load IAP. I have checked things several tiles in ASC and in code. What can I do to fix this?

Hello, We are experiencing an issue with App Store Connect and would like to know if anyone has encountered the same problem. Current status: Our app is already approved and live on the App Store. We created three new auto-renewable subscriptions. All three subscriptions have been stuck in "Waiting for Review" for several days. The subscriptions can no longer be edited (localization and review information are locked). The app review has already been completed, so there is no active app review in progress. During this period, Apple System Status reported an App Store Connect incident affecting submission of In-App Purchases and subscriptions. Since that incident was resolved, the subscriptions are still stuck in Waiting for Review. We have already contacted Apple Support and App Review multiple times but have not yet received any response. Has anyone experienced subscriptions remaining permanently in "Waiting for Review" after the App Store Connect maintenance? Is there anything that can be done from the developer side, or does this require Apple to manually reset the review state? Thank you.

Our app sells two auto-renewable subscriptions. Product loading succeeds and returns both products with correct localized prices, but every purchase attempt fails roughly one second later with "Item Unavailable". No purchase sheet is ever presented to the user. The app has not yet passed its first App Review. It was rejected under Guideline 2.1(b) because the reviewer encountered this same error on their device. MY QUESTION Under what conditions does StoreKit reject a purchase with "Item Unavailable" for a product that has just been returned successfully, with a valid localized price, by a product request? Is an auto-renewable subscription transactable in the sandbox environment for an app that has never had a binary approved by App Review? Question 2 is the one I most need answered. App Review's rejection states that In-App Purchase products "do not need prior approval to function in review", but neither we nor the reviewer can transact them. DIAGNOSTIC LOG Captured on-device during a failing session: 01:08:56 fetchProducts [com.aurascanner.app.pro.weekly, com.aurascanner.app.pro.annual] 01:08:56 fetchProducts -> 2 product(s): com.aurascanner.app.pro.annual=$39.99; com.aurascanner.app.pro.weekly=$6.99 01:08:56 requestPurchase sku=com.aurascanner.app.pro.weekly 01:08:57 purchaseError: code=purchase-error msg=Item Unavailable 01:08:57 error code=purchase-error, storefront=USA 01:09:05 fetchProducts -> 2 product(s), same prices returned again 01:09:05 requestPurchase sku=com.aurascanner.app.pro.annual 01:09:06 requestPurchase threw: Item Unavailable 01:09:06 error code=purchase-error, storefront=USA An introductory-offer eligibility check earlier in the session also succeeded, using the subscription group ID read from the loaded product. So product metadata, including the subscription group, resolves correctly. CONDITIONS Fails identically for both products, on every attempt. Reproduces in TestFlight on our own devices and Apple IDs. Also failed during App Review on iPad Air 11-inch (M3), iPadOS 26.5.2. Storefront reports as USA in every case. Real devices only. Not reproduced on Simulator. ALREADY VERIFIED Paid Applications Agreement: Active, banking and tax information complete. In-App Purchase capability: enabled on the App ID at Certificates, Identifiers & Profiles. Bundle identifier com.aurascanner.app matches the App Store Connect record. Both subscriptions: complete metadata, review screenshots uploaded, USD pricing set, United States availability. Both subscriptions and the subscription group are attached to the current submission, status "Ready for Review". Subscription group has a localized display name. Build distributed via TestFlight, which routes purchases to sandbox automatically. IMPLEMENTATION The app is React Native and uses a wrapper library over StoreKit 2, but the error text originates from StoreKit rather than the wrapper, and the call order follows the documented pattern: Initialize the StoreKit connection. Load products. This succeeds and returns both products. Register transaction update and error listeners. Request the purchase. This is where it fails. Purchases are verified server-side using Apple's App Store Server Library, and the transaction is finished only after verification succeeds. I am not asking anyone to debug the wrapper. My question is about StoreKit and App Store behaviour: what causes the store to quote a product and then decline to sell it? Any pointers appreciated. I can supply screenshots or the full log.

We are implementing StoreKit External Purchase Link for an iOS app distributed in the European Union and are trying to determine whether we are missing a configuration step or encountering a StoreKit server-side eligibility issue. The failure is reproducible in a focused native Swift Xcode project that directly calls StoreKit: let eligible = await ExternalPurchaseCustomLink.isEligible The sample contains no Flutter code, PayPal SDK, networking, or application business logic. Configuration we have verified: The Account Holder accepted the StoreKit External Purchase Link Entitlement Addendum for EU Apps. StoreKit External Purchase Link is enabled and shown as Assigned for the App ID. The regenerated Development provisioning profile contains com.apple.developer.storekit.external-purchase-link = true. The installed app's signed entitlements contain the same value. The application-identifier and team-identifier match the intended App ID and team. The compiled Info.plist contains SKExternalPurchaseCustomLinkRegions with all 27 lowercase EU region codes, including "de". Germany is available for the app in App Store Connect. No local StoreKit Configuration file is enabled. Test environment: Physical iPhone running iOS 26.5.2 (23F84) Xcode 26.6 (17F113) Real German Media & Purchases Apple Account German Sandbox Apple Account StoreKit 2 storefront ID 143443, country code DEU StoreKit 1 also reports country code DEU AppStore.canMakePayments = true AppTransaction verifies in the Sandbox environment Clean build and reinstall using the regenerated Development profile Observed result: ExternalPurchaseCustomLink.isEligible = false For diagnostic purposes only, after observing false eligibility, we also requested both token types: ACQUISITION: StoreKitError.notAvailableInStorefront SERVICES: StoreKitError.notAvailableInStorefront A delayed recheck still reports storefront DEU and isEligible=false. Our production flow does not request tokens unless eligibility is true. We found the similar thread "Unable to enable eligibility for External Purchase Link APIs" (https://developer.apple.com/forums/thread/808349). In that case, the production Media & Purchases account had an unsupported storefront. In our case, both the real Media & Purchases account and the Sandbox account are German, and StoreKit itself reports DEU. We also found "External Purchase in Japan" (https://developer.apple.com/forums/thread/822618), where an Apple App Store Commerce Engineer requested a Feedback Assistant report with a sysdiagnose and screen recording for isEligible=false. Questions: Should ExternalPurchaseCustomLink.isEligible return true in a developer-signed Sandbox build when the entitlement, compiled Info.plist, German storefront, and account conditions are all satisfied, or is TestFlight/App Store approval required? Is there any additional App Store Connect storefront election, entitlement approval, or server-side activation step required beyond the EU addendum, Assigned capability, signed entitlement, and SKExternalPurchaseCustomLinkRegions? If this configuration is complete, could Apple verify whether eligibility has not propagated correctly for the German Development/StoreKit Sandbox environment, and which diagnostics should be included in a Feedback Assistant report? We have also opened a code-level support request and prepared a minimal native Swift reproduction project. Any guidance from StoreKit engineering would be appreciated.

Hi everyone, I'm investigating an issue related to StoreKit 1 receipt validation and would appreciate any insight from Apple engineers or developers who have encountered this before. Environment StoreKit 1 Consumable In-App Purchase iOS 16 / iOS 17 / iOS 18 (observed on multiple versions) Receipt validation performed on our server Receipt is read from the app bundle after the transaction completes Issue Occasionally, after a purchase succeeds and the transaction reaches the SKPaymentTransactionStatePurchased state, the App Receipt exists and can be decoded successfully, but the receipt contains: { "receipt": { ... "in_app": [] } } The in_app array is completely empty. As a result, our server cannot find the purchased product in the receipt and cannot complete receipt validation. Questions I'd like to understand under what circumstances Apple may return an App Receipt where receipt.in_app is empty. Specifically: Is it expected behavior that receipt.in_app can be empty after a successful consumable purchase? Could this happen if the app reads the receipt before the receipt has been updated? Is there any possibility that calling finishTransaction: before reading the receipt could cause the purchase record not to appear in receipt.in_app? If receipt synchronization is delayed, what is Apple's recommended approach? Wait and retry? Issue an SKReceiptRefreshRequest? Or validate using another mechanism? Are there any documented scenarios where Apple intentionally returns an empty in_app array? Additional Information The transaction state is Purchased. The purchase callback is received successfully. We have confirmed that the receipt file exists. The issue occurs only occasionally and cannot be reproduced consistently. Most purchases contain the expected in_app entry. Any clarification about the expected behavior of the App Receipt or recommended best practices would be greatly appreciated. Thank you!

Summary: In Sandbox, Product.products(for:) returns all 3 of my IAPs with correct JPY prices and Japanese localizations, but product.purchase() fails immediately — the payment sheet is never presented — with ASDServerErrorDomain Code=3504 (Product.PurchaseError.productUnavailable).

Environment App: Negaiboshi — Apple ID 6794682125, Bundle ID app.negaiboshi, Team 778QPP83C4 App status: first submission in preparation (never reviewed); build 1.0 (1) on TestFlight IAPs (all "Ready to Submit" since 2026-07-27 JST, attached to the 1.0 submission): app.negaiboshi.pro.monthly (auto-renewable, ¥480, group 22264517), app.negaiboshi.placement (non-consumable, ¥720), app.negaiboshi.nightsky (non-consumable, ¥1,200) IAP base country: Japan (JPY); availability 145/175 countries Device: iPhone, iOS 26.5.2; development build from Xcode; StoreKit Configuration = None Sandbox Apple Account: (address in FB24067333), region Japan, no purchase history; signed in under Settings > Developer Storefront.current = JPN. No Screen Time restrictions. Actual error (verbatim): Error Domain=ASDServerErrorDomain Code=3504 "このアイテムは見つかりませんでした。" UserInfo={AMSServerErrorCode=3504, client-environment-type=Sandbox, storefront-country-code=JPN} TN3186 checklist fully verified, none apply (Paid Apps Agreement, banking, tax all active; bundle ID + IAP capability; signing; membership). Also tried: Sandbox sign-out/sign-in, device restart — no change. Consistent across all 3 products and relaunches. Reproduced with zero app code involved (decisive): Settings > Developer > Start Transaction with product ID app.negaiboshi.placement and bundle ID app.negaiboshi fails: "The provided product ID or bundle ID is invalid. [Environment: Sandbox]" — Apple's own OS-level tool, no third-party code. Calibration: a deliberately nonexistent ID (app.negaiboshi.zzz) yields the identical error — the backend treats my real product like a nonexistent one. A price change (¥720→¥700, "now", 2026-07-29) propagated to the sandbox metadata catalog within minutes (products(for:) returned "¥700") — purchase() still 3504. Reverted. A full base-country change (2026-07-30): Japan (¥720) → United States ($4.99) at 15:52 JST — this deletes and recreates the price schedule and is the exact operation that resolved the identical symptom in thread 839557. It propagated to the metadata catalog (auto-converted ¥800 shown in ~20 min), yet purchase() and Start Transaction still failed at 16:10 and 16:55 JST. Reverted to ¥720 at 16:59 JST. Every lever that rewrites the price schedule reaches the metadata catalog but never the commerce/purchase catalog. Timeline: the products reached Ready to Submit hours after the 2026-07-26 15:22–17:58 PDT In-App Purchases outage (Message ID 1000005803), and the failure still reproduces after the 2026-07-29 16:20–19:30 PDT emergency maintenance on In-App Purchases + Advanced Commerce API (messageId 1000005805). Peer reports with the same metadata-vs-commerce-catalog split in the same window: threads 839220, 839441, 839437, 839645, 839557. Questions: Why does purchase() fail server-side with 3504 ("item not found") while products(for:) succeeds for the same IDs in the same JPN storefront? Can someone check the sandbox commerce-catalog state of the 3 product IDs above (Apple ID 6794682125)? This looks like a server-side provisioning failure that no developer-side action can repair. Is any additional App Store Connect state required before sandbox purchases can complete for a never-yet-reviewed app?
