Our app can no longer complete native Sign in with Apple: the system sheet appears, the user authenticates (Face ID / password succeeds), and the sheet then fails before any credential is returned to the app. Console shows AKAuthenticationError -7003 from the AppleAccount/AuthorizationServices stack. Details: App: "Antes y Después: Fotos" — bundle ID com.jpbaldi.antesydespues, live on the App Store Team ID: PZDWZHXF9V (individual membership) Implementation: ASAuthorizationController (via expo-apple-authentication), scopes full name + email; the identityToken is exchanged with our backend (Supabase). The failure happens inside the native sheet, before any token is issued. Reproducible across devices, networks and Apple IDs — and App Review reproduced it too: our build was rejected under 2.1(a) because the reviewer hit the same failure. It does not look device- or account-specific. What we've already tried, with no change: Removed and re-added the Sign in with Apple capability on the App ID in Certificates, Identifiers & Profiles, regenerated provisioning profiles, rebuilt and resubmitted. Verified com.apple.developer.applesignin (Default) is present in the shipped binary's entitlements. Fresh devices, different Apple IDs, different networks. As a workaround we shipped v1.0 with Sign in with Apple disabled (email/password only), so guideline 4.8 doesn't apply — but we want to restore it. Since -7003 appears to be returned server-side for our client ID rather than by anything in the app, is there any account-side registration state for the App ID that can be checked or reset? Has anyone resolved this exact error without creating a new App ID (not viable for a shipped app)?
