Sign in with Apple fails with "Sign-Up Not Completed" Team A884B34HZR
The authorization sheet renders correctly with our app name and the user's Apple Account. After the user authorizes, it ends with "Sign-Up Not Completed" and no credential is returned to the app: our delegate receives no credential, and our server never receives a request.

Already tried, with no change:
- Removing the Sign In with Apple capability from the App ID, saving, re-adding it as a primary App ID and saving again.
- Regenerating the provisioning profile and shipping a new signed build.
- Several Apple Accounts, on Wi-Fi and cellular, on iOS 26 and iPadOS 27.
Our submission has been rejected under Guideline 2.1(a) because of this. This looks like the same server-side registration failure reported in threads 789452 and 837986.
