Ok, as the Plex team hasn’t fixed this yet I went and did a bit of playing around and found a workaround to this issue (the whole Plex not loading metadata retrieved by 3rd party agents).

It kinda looks like there’s a white list of some kind for metadata agents, the fix is pretty simple if not infuriating:

Goto your “Plex Media Server\Plug-ins\xxx.bundle\Contents” folder (xxx being the affected bundle) Open up the “Info.plist” file Find the line that says “com.plexapp.agents.xxx” and change it to “com.plexapp.agents.thetvdbxxx” (xxx being the affected bundle) Goto your “Plex Media Server\Plug-in Support\Data” folder Rename the “com.plexapp.agents.xxx” directory to “com.plexapp.agents.thetvdbxxx” (xxx being the affected bundle) Restart Plex Check your agent setting (might have reset) (optional) Rematch any show with missing or incorrect metadate (posters , etc)

The above steps are taken at your own risk but using the I’ve managed to fix all my agents
