So, I add my TV shows to plex. It scans them and downloads meta data correctly and displays everything in my library. Titles are correct and they play. But as soon as it’s done fetching everything it goes through one by one and removes them all from my library. I’m at a loss.
I know this sounds silly, but on the top of the webpage on your plex: movies do you have it on recommended vs library? For some reason mine defaults to recommended and depending on the folder I am looking at, nothing is there. When I click on Library they magically appear.
I am by no means an expert on the platform, just sharing what I have encountered.
Good luck.
