I created an app record in App Store Connect and uploaded a single TestFlight build. The app was never submitted for review and never published. No testers were added, there are no In-App Purchases, no Services IDs, no Sign in with Apple groups and no app extensions.
I then removed the app record from App Store Connect (it now shows under "Removed Apps").
When I try to delete the corresponding App ID in Certificates, Identifiers & Profiles, I get:
"There is a problem with the request entity
The App ID '***' appears to be in use by the App Store, so it can not be removed at this time."
Questions:
1. Is there any way to permanently delete the app record (not just "remove" it) so that the App ID is released?
2. Does the App ID ever get released automatically — for example after the TestFlight build expires, or after some waiting period?
3. If not, is there any process through Developer Support to have it released?
I need this exact bundle ID to be registered under a different developer account. App transfer is not an option since the app has no released version.
