Just installed Enpass and paid for pro based on a bunch of recommendations. Running this in Chrome Version 60.0.3112.90 (Official Build) (64-bit) I get no window, popup, anything available to me as far as logging into any sites I've put into the password manager app. The app is running on my desktop, Windows 10.
If I got to a site (like amazon) where I have a login and right-click the username and password fields, I do get an option for "Enpass" but selecting that just pops a new Chrome window that goes to my homepage.
Basically, autofilling doesn't work out of the gate...
