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

@xyzulu

Our developers are indeed investigating an issue with Face ID / Touch ID. A diagnostics report allows us to verify that the user is affected by the known issue rather than by a different issue that would need to be investigated further which is why support may have asked you for a diagnostics report before confirming that you're affected.

Our developers are aware that this issue is affecting a number of users and they're treating this as a priority. I'm sorry for the inconvenience that the issue is causing. If you're interested, my colleague Jack has a posted a workaround however it should only be attempted by technically savvy users who are comfortable with factory resetting their iPhone and restoring from an iCloud backup (since data loss is possible): https://1password.community/discussion/comment/657234/#Comment_657234
