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

Hi,

Note this isn’t the known safari extension issue, this is completely outside of safari:

I got an iPhone 14 Pro yesterday and restored from my iCloud backup. Once I logged in, 1Password worked totally fine with Face ID and Autofill as expected. But for other reasons I decided to do a full settings reset on my phone (not a factory reset, just settings) and now Face ID and Autofill don’t work at all.

When I try to click the key button when logging into any app, Face ID scans my face then gives me in the 1Password window a message saying “that didn’t work.” I then have to enter my master password to get my logins. Autofill suggestions never show up above my keyboard, only the lock icon, even if I’m logged into the app and it hasn’t timed out (face ID doesn’t work on the 1pw 8 app either)

I’ve verified 1Password is checked in the iOS Autofill settings. I’ve verified Face ID is turned on for 1Password both in app and in iOS settings.

I’ve tried logging out of 1Password and logging back in (both with the remembered email address and with a fresh re entry of secret key etc)

I’ve tried turning Autofill and Face ID off then back on.

I’ve tried the above but with a power cycle in between turning off and back on.

I’ve tried an erase of the app and then repeated all of the above troubleshooting steps.

No matter what I get these errors when I try to use Face ID and Autofill. Works totally fine on my Mac and PC. This app is really frustrating to use without Face ID and Autofill - any known solutions?
