I got it going and syncing between my Android phone and my Mac via Google Drive. I had to do a backup in Enpass6 Beta, remove any places Enpass5 or Enpass6 Beta were installed and told it to remove my shared Google Drive data; it did upgrade Enpass5 on my phone (I had both installed) but the install did not remove Enpass6 beta for me on any of my platforms so far (I have a linux box to try later when I get home). Once any old installations were cleaned up, I went to the phone, choose restore over Wifi and uploaded the backup I just did. I then told it to sync via Google Drive, and it's working fine so far.
