Maybe I shouldn't have written "Autofill". Enpass puts in the login and password correctly, that works fine.
What I mean is the "Save and fill basic info" functionality of the Edge browser which I've been using to fill address, date of birth, name, etc. into forms on websites. That doesn't work anymore because Enpass has switched off and disabled (grayed out) the slider button in the browser settings for some reason. And I'd like to enable it again to get that functionality back.
