This issue has gone on since early December of 2017, I never had this issue until an update around in December of 2017.
It will find my shows but sometimes not exactly match them at all so I’m left manually entering the titles and the rest of the metadata myself instead of relying on Plex to find them for me. I have tried everything the forum admins help don’t quite work I had this working with TMDB instead of TVDB for awhile now neither work for my shows. I use to love plex until it became frustrating to deal with this issue I am seriously thinking about switching over to Emby now. Plex will rescan my shows and the shows that will have the metadata already suddenly vanishes too so I have one or two or more shows that had its metadata then ripped and it cannot find it anymore whatever your devs are doing I sure hope they know wtf they are doing! Because of it sure as hell doesn’t seem like they do to me if they managed to screw things up for 7-8 months
