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. Bundle ID: com.dinogoal.ios (created in 2026) Feedback: FB24978334. Developer Support case: 102979104342 (closed without a resolution) 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.
