Sorry to report that did not work for me. I reset all the biometrics settings on both the desktop app and the browser extension (I tried Chrome, Edge and Safari), but it keeps happening. My exact symptom is that I click on the “Unlock with biometrics” button in the browser extension and it does nothing. I have to then go to the desktop app, click that button to unlock the desktop app, then return to the browser extension and click the button there, and then I get the prompt (via the desktop app) and it works. Whew.
