Android client (Xiaomi Mibox S) always transcodes even though is set to play original quality

I have tested the beta and I’ve found the following:

  • no subtitle: direct play, freeze & restart after 10-15 min
  • subtitle: error message, fails to play
  • setting subtitles to burn always from automatic, plays the movie with transcoding.

On top of that there is constant restarts of the plex app.

Testing environment:
Wired connection with TP-link ethernet usb adapter
App settings: everything maximum settings, auto adjust off
