Same issue, same signature — Team ID F3THR995U3, bundle ID com.todaywe.app (App Store Connect app 6801750747), App ID created 2026-08-15. Native sheet renders, user authenticates and gets through the name / Hide My Email step, then "Sign Up Not Completed"; ASAuthorizationError 1000/1001 with empty userInfo; zero requests reach our backend. Reproduced by App Review on iOS 26.6 / 26.6.1 / iPadOS 26.6 across three builds; rejected four times under 2.1(a). Capability (APPLE_ID_AUTH, PRIMARY_APP_CONSENT) and the applesignin entitlement in both the embedded profile and the code signature of the submitted binary are verified; all agreements active; removing and re-adding the capability did not help. Feedback ID: FB24504521. Requesting the same server-side team registration fix that resolved GW7XA5CX69 and FRL3DTJQ62. Thank you.
