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

Any updates on this. I have upgraded to 1Password 8 for Mac. I also had to re-set my iPhone settings and since then I cannot use Face ID to open 1Password. I have re-installed the 1Password app, checked to make sure 1Password is approved for using Face ID on my phone. App ‘acts’ like Face ID passed but requires entering password always. Very frustrating.
