Same issue here. We use ASWebAuthenticationSession to login.
From what I see in the error the App displays on screen. It looks like a web credentials issue when they test it.
On my side, I checked again and again, every thing is fine. I can log in successfully. With previous App Store App, with the same binary in TestFlight.
The entitlements are correct in the App, the server are up and running, with correct app-apple-app-site-association files
Review device details:
Device type: iPad Air (5th generation)
OS version: iOS 17.6.1

Hello, after several unsuccessful attempts yesterday afternoon (Europe/Paris time). We generated 1 private key again this morning. And the generated Key seems to be functional.
