Hello,

A user on my Plex server is experiencing several issues when playing videos from the Plex mobile app. Here are the specific problems:

  • When switching subtitles or audio tracks, the changes are not applied immediately. He has to close the video and restart it for the modifications to take effect.
  • If he tries to seek (rewind or fast-forward) after changing a subtitle or audio track, the changes still don’t apply, and he often encounters a “Source: bad HTTP status” error, closing the video.

To confirm, I tested this myself on my own mobile app and I am experiencing the exact same issues. On the other hand, everything works perfectly fine when testing via a web browser or the Android TV app.

Has anyone encountered this problem before?

Hi @donut.chief ,

Thanks for your reply. Indeed, the issue seems very similar. I’ll share what I’m experiencing on that other thread.
