Team ID: ZJ2GMC59A6 Bundle ID / Client ID: com.petsboss.app Existing support case: 20000139348366 Feedback ID: FB24131409 (Sign in with Apple fails with ASAuthorizationError 1000 ("Sign Up Not Completed") despite valid entitlement, primary App ID, and active membership ) The native Sign in with Apple sheet completes Face ID authentication, then displays “Sign Up Not Completed”. ASAuthorizationController returns ASAuthorizationError.canceled (1001) with no credential or identity token. The signed provisioning profile contains: application-identifier = ZJ2GMC59A6.com.petsboss.app com.apple.developer.applesignin = [Default] The App ID is configured as a primary App ID. The failure occurs before any request reaches Supabase. This matches Apple Developer Forums thread 837986, where affected teams reported Invalid client / AKAuthenticationServerError -24000 and were resolved by server-side re-provisioning with no client-side changes. Please route this case to the Sign in with Apple / AuthKit backend team and inspect or re-provision the server-side registration for this Team and Client ID.
