I have been submitting the app multiple times, and I keep getting rejected on Guideline 2.1 - Performance. Specifically, the in-app purchase is not available and the app is unresponsive when we tap the Upgrade button.
I have tested the wiring and it works, the issue is that the subscriptions are not approved because:
"Your first subscription must be submitted with a new app version. Create your subscription, then select it from the app’s In-App Purchases and Subscriptions section on the version page before submitting the version to App Review."
So I can't get the subscriptions approved without the app approved, but I can't get the app approved without the update option to work.
I seem to be stuck in a loop. Please assist.
