Server Version#: 1.21.1.3876
Player Version#:7.11
If I sync movies or tv shows to my phone for offline viewing, the progress never synchronizes either way. If I watch a movie offline, when I connect again to Plex it does not sync to the server. If I have a movie downloaded and start watching at home, that progress never gets synced to my offline version. This makes the entire syncing feature unusable.
