Automatic biometric login seems to have stopped working

On macOS, automatic pop-up of the biometric login (“Ask for Touch ID on launch”) seems to have stopped working recently.

Happens to me as well from time to time. Have you tried restarting the app? That helps usually.

Yes I have tried restarting the app. That is the whole point—when I restart the app, the biometric login prompt does not automatically show.

What do you have “Vault Timeout” set to?

I have “Vault Timeout” set to “On restart”.

IIRC I have always had it on that setting.
