< TL;DR: If I play a video with VOBSUB subtitles on Plex, CCs are disabled across all apps on the Roku. After playing a non VOBSUB video or stream on Plex, CCs reappear across all apps on the Roku>
Observed behavior:
- Play a personal Plex server video with embedded (VOBSUB) subtitles (i.e. not a channel or title streamed from Plex) until a subtitle appears. Exit Plex.
- Play any stream from another app that is expected to have CC – the CCs are not playing; confirm in multiple apps
- Go back to Plex and play a Plex server video or Plex channel or title streamed from Plex, until a CC appears. Exit Plex.
- Play any stream from another app that is expected to have CC – the CCs are now playing; confirm in multiple apps
Not sure what other trace detail you need, but I can reliably replicate this each time.
