I have two plex servers,in different locations, synced using rsync and plex-sync.
If I watch a movie at location A, location B does not know about it. This means that i have to choose the A server when I am physically at location B to resume.
Not sure why plex-sync does not handle this. But anyway, if I resume from location B, does plex play the local media,file, or the remote? Finding it difficult to tell, even with plex dash.
