Looks like my backups are failing. I keep getting "Failed to backup Device Data. A server error has occured." This seems to happen during backup of the "Apps". I cna see other pieces backed up OK. I tried 5 times already and rebooted, etc. Hmm.
I just tried backing up my apps and it was successful. The display of how much space I'm using did not change so I don't fully understand what it backed up. When you click on the space you have available it shows you what is taking up space and all of the manual backup items aren't in there.
Maybe I just don't understand how this is supposed to work. I need someone with a Note 7 on another carrier to confirm the behavior of Samsung Cloud.
