Ratings and reviews

Edit: as of today, possibly prior, I too am getting backup failures. When I unlinked my account then tried to link it again I get "this app is currently disabled". Is this an issue with DB or with the John cloud backup thingy app? Never worked on my note 8, both note 20 and teclast m40 now not backing up, never even got to install on my galaxy tab a8.

It doesn't work properly at the moment. The saves backup works but the games back up just says "Completed successfully" immediately without backing up anything. It'll be cool if it could back up to other services besides Dropbox. People that use emulators are often tech savvy, so an option to backup to personal clouds would be really cool. Even if it is through something basic like SFTP.

I like this app, but I'm having the same issue everyone is having right now. It looks like the issue happens when you re-install the app because I just got a new phone and it's not working when I try to link with my Dropbox. (please fix so I can give you 5 stars)
