Routinely subtitles are not being displayed even when they work correctly on the server and are part of the mkv file already
On the rare occasions that the system can find a subtitle file for an episode, that still rarely shows.
If you have multiple versions of an episode then there is no chance whatsoever of the subtitles being displayed.
