Lately I found that Plex is not recognizing when a new subtitle is added.
Regardless of the filename, folder name, extension, etc. the subtitle won't be shown on Plex.
Don't know whether is a problem from Seedboxes or Plex. However, to try, I've created a Plex server locally in my computer and added it to my TV and in that case the subtitle was properly recognized and displayed.
Is there any setting, or fix, for this?
