Since the last update I'm constantly receiving multiple times per day:

Error 403
Enpass app has denied access to data.

code : 1
origin : chrome-extension://kmcfomidfpdkfieipokbalgegidffkal
path
port : 59932
server_port : 10391

Browser extension version: 6.11.18
macOS desktop version: 6.11.18

The only solution for this is to restart Enpass desktop app.

I'm getting the same. What browser are you using? I'm using Dia Browser and wondering if that has anything to do w/ it https://www.diabrowser.com/
