Face ID Not Working [Fixed. Please see the approved answer for details.]

I just heard back that it’s a known issue. This is what I got from support:

“Hi Steven,

Thanks for your reply. My name is Kester and I work for the Mac and iOS team here at 1Password support. After looking at the diagnostics report from your device, I can confirm that you are experiencing a known issue, where 1Password 8 for iOS fails to unlock after successfully prompting for Face ID. Our development team is investigating and are working on a fix.

Whilst our developers work on a fix for this issue, we have the following workarounds:

Continue using 1Password 8 and unlock with your account password each time.

Re-download 1Password 7 which will allow you to unlock the app with Face ID until a fix is available in 1Password 8.

Follow our step-by-step instructions to reset your iOS device and restore from an iCloud backup. We've seen this method restore Face ID unlock functionality in 1Password 8, but it can lead to potential data loss. We'd only like to offer these steps if you're comfortable with the process and understand the risks.

Let me know which workaround you'd like to move forward with and I'll be here to help. 🙂

Looking forward to hearing from you.”
