Same here. Just setup today with latest on both Android Note 3 (4.4.2) and Win 7 PC. Have working with internal storage (/storage/emulated/0) but cannot see external where most of my data is to back up. Might I add noting you can copy the URL in the email to the key text field in the app would be nice. Finally tried that in desperation after could not get to work in IE, Chrome or Firefox.
