Browser biometric unlocking stopped working

I unlocked the browser extension using biometrics via the desktop app. Has worked flawlessly for ever but now it just says “Awaiting confirmation from desktop”. The unlock prompt does appear in the app but then nothing.


I tried disabling biometrics in the extension and re-enabling but now I can’t turn it on. Windows 11 23H2 - note very latest feature pack?

I tried removing and re-adding the extension with no effect (Edge) but I did notice this prompt which I’m sure sure I recall before:


I said allow but no difference. Will try once more.
