I've tried that, several times. I've also tried starting and stopping the sync, as is suggested, and quitting and then restarting the Creative Cloud desktop.
It's very frustratring. When I run the sync procedure again, it takes forever and ever, and then it indicates other files (which synced correctly in previous attempts) have not synced. 😳
With the same, unchanged set of files, I sometimes get 1 file that hasn't synced. I also have gotten the result that 4 files haven't synced (with the same set of files), 11 different files haven't synced, or 28 files haven't synced.
I don't know why a file that hasn't been changed will sync properly one day, and then not sync the next. But that is what seems to happen and these synch problems are taking up an awful lot of time, and a lot of aggravation, with software I pay a lot of money to use.
I didn't have these problems with (free!) Google Drive or (free!)Dropbox. Why do I have this problem with this program that sucks money out of my bank account every month? 😡
