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

@xyzulu

I'm sorry for the confusion. My colleague Grey said it best in the thread that you linked:

Face ID and Touch ID in 1Password 8 on iOS are currently a very high priority for our development and customer support teams. The development team have found the cause of the problem and the relevant secure parts of iOS that 1Password communicates with. They are working on building a solution for the root cause of the problem and although it may not seem like it from the outside, there has been considerable discussion about this issue within the teams. I assure you, we do know about it, and the impact that it's having on customers. We're hoping to have something concrete to announce in that regard soon.

Thank you for your patience.
