I use Creative Cloud to store all my project files. While working, I frequently get the popup message "Unable to sync ...." whatever project file I'm currently working on. This happens about 20 times per day, so it's a little annoying. Eventually it always gets synced, just a little late I guess. It's not a one-time maintenance thing, as this has been happening every day for the past couple of weeks.
I have emailed you about resolving this issue.
