App rejected by Apple Review due to Google/iCloud sign-in bug on iOS 26.3 - anyone else?

My app was rejected because Apple’s reviewers couldn’t sign in with Google or iCloud on iOS 26.3. The problem is, I can’t reproduce the issue on any iOS 26.x version, including 26.3.1, which I suspect actually fixes whatever was broken in 26.3.

I’ve replied to App Review asking for more details and a screen recording, but now I’m stuck waiting 3 days for a response while Apple’s own review system is apparently still running the buggy 26.3 build.

Has anyone else been rejected for this recently? And does anyone know if there’s a way to get the iOS 26.3 simulator runtime now that Components only offers 26.3.1?

Any tips for speeding up the back-and-forth with App Review in a case like this would also be appreciated.
