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

After looking at the diagnostics report from your device, I can confirm that you are experiencing a known issue
Well since this thread. was started in August I would say it's been a "Known Issue" for quite sometime. How can this possibly take so long to remedy. I'm not paying to, reset my phone, downgrade to 7 or put the password in every single time I want to unlock 1Password. I don't understand how we can still be expected to pay full price for something that does NOT work as it is supposed to. It sure would be nice to hear from someone with something concrete to say other than "Thanks for the update" from Nov 23.
