We operate a small radio station. Computer A is the system that automatically produces playlists and constantly updates them by the hour. The issue is we rely on Dropbox to sync from that computer to several others in the chain. Conversely, the other systems are also supposed to send info to Computer A. None of the other systems are syncing with Computer A in either direction. For some reason the last time it worked correctly was on 9/14. I am now stumped on where to look.
