All files are named Late.Night.with.Seth.Meyers.<YYYY-MM-DD>.<Episode Name>.<Info>.mkv, but the Originally Available date in Plex is always one day before. (Eg, if the filename date was 2024-05-09, the Originally Available date in Plex would be 2024-05-08), and then the episode match is also one day off.
Is this a timezone issue? Timezone on server is UTC+02:00.
As I’m sure you know, plex uses a single consolidated metadata. Changing from TMDB to TVDB may change the order of the episodes, it has little to no effect on the metadata itself.
Possibly so, but then we have After Midnight which airs the same time as Seth Meyers, but those episodes are correctly matched. If I look at TMDB, the metadata about the episodes for both shows looks the same, but Plex matches them differently.
