I use the CC on Mac and on Windows, actually a very good tool but it doesn't synchronize the same on these two platforms.
On windows is always an exclamation mark in red (something went wrong) and some data is missing. I have no clue what the problem could be because on Mac everything is fine.
Well, what is actually being synced? You need to be more specific.
I am trying to sync my data, that means folders with InDesign files and related pictures etc.
Actually a usual InDesign folder...
