Movie plays fine with subtitles for a few minutes (1-3 minutes) then Chromecast disconnects and displays “Something went wrong” message.
Player device shows dialog “Resume on this device”.
From the logs it seems the transcoder is active (probably due to the subtitles). Will try to play again without subtitles and report the results.
