I had to downgrade to an earlier version of Plex Media Server. I also put each individual movie in a folder, for I always hated doing the Plex dance, when I have multiple versions of the same movie. It keeps it nice and tidy for me. Not sure why the update would mess everything up that way, but saying to just use the Parent folder only doesn’t solve this vexing problem. I wish Plex had a phone support, for this is something we should be able to get tech support from and not try to guess at it or wait for forum help.
