/Scooby-Doo! Mystery Incorporated - S02E01 - The Night the Clown Cried (1080p WEB-DL x265 HEVC 10bit AC3 2.0 RCVR) [UTR].mkv*
And it only ever seemed to find 2 episodes out of the season. Originally, the folder names also had “Season 1” or “Season 2” in them, but when i removed that, suddenly it found 20 more episodes in season 2 yet only 4 more in season 1. When i started to strip the filename down to something more simple like “Scooby-Doo! Mystery Incorporated - S01E01 (1080p WEB-DL x265 HEVC 10bit AC3 2.0 RCVR) [UTR].mkv” then plex saw it! I couldn’t find anything about this online so I thought I would post it here so someone could see. I understand the more logical thing to do would be to just not have filenames that are so long but I feel like it’d be good for plex to account for this.
Plex has no limit. Windows however does have a 260 character limit for paths, but you’re not there yet. Your filenames themselves are likely the issue.
