Since 2026-11-14 00:56 UTC, about 45% of people creating a new account with Sign in with Apple in our App Store app fail. The sheet appears, the user picks Share or Hide My Email and confirms with Face ID, then the delegate gets ASAuthorizationError 1000 with an empty userInfo. Customers report a system "could not connect" alert just before it.
What we see:
- Only first-time authorizations fail. Returning users sign in normally.
- Only iOS 26.x and 27.x. No failures on iOS 18.x.
- Same rate in Japan and Thailand, on Wi-Fi and cellular, with either email choice.
- An affected device fails on almost every attempt, then eventually one attempt succeeds. Unaffected devices succeed first time.
- 1,340 failed attempts from 376 devices so far. The same build signed in 107 of 111 users in the two days before it started.
- No app release, App ID change or backend change at the time. System Status shows Sign in with Apple as available.
We have not been able to reproduce it on our own devices, so we have no sysdiagnose from a failing device yet.

Is anyone else seeing this since November 14? And could someone from Apple check the server side for our client ID?
