I've enjoyed using Enpass for a couple of years now, purchased a license too. However, as of late my Enpass window keeps "Not Responding" when I try to use it. I've uninstalled it, removed all registry entries and reinstalled it. This has not solved the issue. I've been installing it from the Windows Store. I've downloaded the manual install as well directly from the Enpass website, but it's doing the same thing. When I use it on my Android phone or my Surface Go (Windows Store version) I have absolutely no issues and it works fantastically.
