It does, once you’ve moved LMA and are getting a solid match. Before that, Lock doesn’t do much of anything other than be Orange.
Proper file names and structures - that aren’t freaked when Plex prefers a bogus embedded title in an MP4/M4V file - are your best avenues to success.
Plex can’t read or react badly to embedded Title Fields in MKV files.
Also note:
Sometimes Plex gets confused or is dealing with an ill formed bundle requiring The Plex Dance for stubborn items that won’t cooperate - after you’ve moved LMA under ALL tabs in TV Shows and Movies.
The Plex Dance is the ONLY sure way to get a complete and utter ‘Do-Over’ by wiping out the current bundle and creating a brand new one - hopefully with all the right stuff in it this time.
It’s odd, but there it is.
