a UK-based user is having trouble completing an in-app purchase.
after going through the typical purchase flow (tapping the button to trigger the in-app purchase sheet, completing Face ID) they see this verification sheet appear over my app and have to go to their banking app to approve the purchase.
after approving the purchase from their banking app, they tap "Payment confirmed on Mobile App" to close the sheet, but then see an alert that suggests the result is .userCancelled.
the purchase does not seem to have completed. the user reports not being charged (despite numerous attempts). plus, i have a "restore purchases" function on App init that would've restored a purchase if it existed.
i have implemented what i think is a typical Storekit.purchase() method (again, the message the user sees is for the .userCancelled case):
func purchase(productId: String) async -> (Bool, String?) {
guard let product = subscriptionProducts.first(where: { $0.id == productId }) else {
return (false, "Product not found")
}
do {
let result = try await product.purchase()
switch result {
case .success(let verification):
switch verification {
case .verified(let transaction):
await transaction.finish()
hasSubscription = true
return (true, nil)
case .unverified:
return (false, "Transaction verification failed")
}
case .userCancelled:
return (false, "No worries, take your time. 😌")
case .pending:
return (false, "Purchase is pending")
u/unknown default:
return (false, "Error purchasing product. If this keeps happening, please contact [email].")
}
} catch {
return (false, "Error purchasing product: \(error.localizedDescription)")
}
}
has anyone dealt with this issue? i was seeing an unusually high number of .userCancelled purchase events from users outside the US, and i'm wondering if some of them were genuine purchase attempts that were blocked by this verification step. 😕
