Re: But…
I think this will cause an issue for lots of people. I have both apps - B&S for personal GDrive and the new app GD for our corporate Google Drive. It works ok. However - like your user, my new app does not have the option to add my personal account either (contrary to screen shots I've seen where this is an option). I have a suspicion its been disabled by our Google Admins, and perhaps not the ARM / Intel issue you are seeing?
