Sign in with Apple fails immediately with ASAuthorizationError.unknown (1000) — new team, capability enabled but never activates

On a physical device, the native Sign in with Apple sheet fails INSTANTLY with ASAuthorizationError.unknown (code 1000) — before any Apple account UI appears. It fails for every Apple ID we try. The app shows "Sign Up Not Completed".

App ID: brp.sohsostory.app · Team: JZZUYHU3UU (a newly enrolled account)

Already verified (config looks fully correct):

  • "Sign in with Apple" capability is ENABLED on the App ID (Primary App consent), confirmed in both the Developer portal and via the App Store Connect API.
  • The active distribution provisioning profile includes com.apple.developer.applesignin, and the built binary carries the entitlement.
  • Program License Agreement is accepted.
  • The SAME client code + backend works on a DIFFERENT (older) team's app, so this looks specific to this App ID / team — as if a server-side activation for a new team never completed.

Questions:

  1. For a newly enrolled team, is there a known activation delay before Sign in with Apple starts working, and how long?
  2. Is there any additional step required to "activate" the capability beyond enabling it on the App ID and regenerating the profile?
  3. Has anyone resolved ASAuthorizationError.unknown that persisted for days on a new team?

Environment: iOS (physical device), React Native / Expo, backend uses Apple as an OpenID provider (Supabase Auth).
