Same signature here. Team ID 4QF8GJDJ5B, bundle ID com.outfitai.outfitai (App Store app Awtfit). Native ASAuthorizationAppleIDProvider, scopes name and email. The sheet presents, the user authenticates, then "Sign Up Not Completed", and the app receives ASAuthorizationError.canceled (1001). Zero successes ever since the feature shipped on 2026-08-30: in the last five days alone 235 taps from 131 devices on 21 iOS versions (18.7 through 27.0), with a median of 11.7 seconds on the sheet before the error, so these are not dismissals. Google sign-in works on the same devices. The entitlement is in the signed binary and the App Store profile; the App ID is a primary App ID with APPLE_ID_AUTH / PRIMARY_APP_CONSENT (enabled through the App Store Connect API on 2026-08-29); agreements active.
