Subtites are not picked up automatically in Plex at all.. One example is:
Apocalypo (2006)
The SRT file is named the same and in same folder as the movie.. Confirmed by playing in VLC, it automatically picks up the subtitle file.
Even tried with “Local media assets” enabled in the Agent, no-go. and “Refresh Metadata” doesn’t help either as indicted in

If i pull down i can select “(Unknown) External SRT”, and that works, but i have to manually do it.
Running version is: 1.41.7.9799
