In-App Purchase subscription products have been in Waiting for Review status for several months

Our app was approved for distribution yesterday, however our In-App Purchase subscription products have been in Waiting for Review status for several months, without the ability or option to manually connect to the app when submitting for review. As a result the App Store is incorrectly displaying our app as a $6.99 one-time purchase instead of Free with In-App Purchases. What can be done to connect the app to the subscriptions.
