I named my file using filebot and plex has been working fine for over 1 year. I got a new PC and moved my Plex server to it and one of my shows isn’t recognized:
Here’s an example of another TV show with same naming convention that is recognized by Plex:
Go to the top level of this show (quickest by clicking on the show’s title)
Edit the show
go to the Advanced tab
Set “Episode Ordering” to “TheTVDB (Aired)”
