Hello,
For many shows when I start binge watching a show, Plex does a great job of knowing what episode I watched last and having me ready to watch the next episode when I watch next. I figure there is a switch I forgot to check.
I’m currently rewatching the Mentalist and it seems to arbitrarily pick what episode or season I watched last. I have every episode organized using the same schema I use for all shows including the ones that doe work. Plex immediately organized every episode correctly when it scanned for the files.
I’m using the latest plex server as a source and a Roku with the latest plex loaded on it as the viewer.
