I began experiencing this issue when there was a widespread meta data issue with TheTVDB on 3/18/2018 but I still can’t resolve it. I’ve tried the following:
Reorganized agents so that local media is not priority
Plex Dance (removing files from library, deleting trash, removing bundles, deleted meta data from local video files, re-adding video files to library, rescan)
I’ve been testing with game of thrones. This was previously mapped but I removed the whole series and now all meta data is blank. Any suggestions would be greatly appreciated!
For example F:\TV\Game of Thrones\Season 06\Game of Thrones - 6x01 - The Red Woman.mkv
would be F:\TV\Game of Thrones\Season 06\Game of Thrones - s06e01 - The Red Woman.mkv
Suggest first to try and do that and see what the outcome will be
