Embedded SRT subtitles not displaying when selected
Hello, I'm having a new issue with certain files that have embedded SRT subs.
Subtitle options show up properly in the Plex UI, and appear properly selected, but do not display on the screen while playing the file.
The subtitles display fine in the Plex web app, as well as other 3rd party PC software.
If I obtain an external subtitle file (also SRT) and select it, THOSE subtitles will display properly on the Roku plex app.
I am using direct streaming (no video transcode) from a server on my LAN, and have the Roku global caption settings set to "always on".
Any tips/tricks for solving this, short of always using external subs?
