Bug: Verification stuck at 5% after scanning QR in zkPassport app

I'm encountering a reproducible issue in the zkPassport app (iOS, downloaded from App Store). After successfully adding my passport (ID scan + chip scan), I scan a QR code from a project to verify my identity.

When I tap “Confirm”, the process freezes at 5% and then jumps back to the screen with the “Confirm” button. No error message is shown. The verification does not complete.
