Face ID sign-in fails after the 6.4.0 update

Accounts migrated to the new authentication stack fall back to the passcode screen, and the passcode is often rejected on the first attempt. Reviewers describe being locked out for minutes at a time.

Face ID no longer works

After the update to 6.4.0 the app no longer recognises Face ID. I end up at the passcode every time and it gets rejected on the first attempt.

Seit Jahren Kunde. Nach dem Update auf 6.4.0 erkennt die App Face ID nicht mehr. Ich lande jedes Mal beim Code und der wird beim ersten Versuch abgelehnt. Bis dahin nur ein Stern.

Can't connect

Face recognition stopped working after the update. I reinstalled the app and it works again, but that shouldn't be necessary.

La reconnaissance faciale ne marche plus depuis la mise à jour. J'ai réinstallé l'application et là ça refonctionne, mais ce n'est pas normal. Sinon l'application est très bien.

Can't sign in after the update

After the last update I can't sign in with Face ID, it keeps falling back to the passcode screen. Even when I enter the passcode correctly it errors once.

Son güncellemeden sonra Face ID ile giriş yapamıyorum, sürekli şifre ekranına düşüyor. Şifreyi doğru girsem bile bir kez hata veriyor.

Client depuis trois ans. La reconnaissance faciale ne marche plus depuis la mise à jour. J'ai réinstallé l'application et là ça refonctionne, mais ce n'est pas normal. Merci de corriger rapidement.

From the reviews

Reviewers who reinstalled the app report it working again, which points at the migrated keychain entry rather than the biometric prompt itself.

Sign-in blocks every other task in the app, so this cluster suppresses the rating far beyond its own share of reviews.
