I am using Linux Mint 18.2 Cinnamon, 64 bit. Browser is Chromium Version 59.0.3071.109 (Developer Build) Built on Ubuntu. The authorization link for Google Drive that you provided me in private message works fine, I'm now able to sync Enpass with Google drive.
Same thing is happening to me but with Google Drive. Enpass works fine on Ubuntu 16.04 but I tried it with Linux Mint 18.2 and while I got it installed, I could not link to Google Drive, it says it's redirecting to Google page but never does. Any solution for this?
