I want to bring this to anyone’s attention to those who use an nVidia shield with Plex. I was having an issue where the now playing information wouldn’t show at the top of the activity and the play button wouldn’t work. It appears after a plex upgrade for nVidia shield it set the enable new video player to ON. If you go to your plex settings and advanced to the right will be enable new video player. If this is set to ON you will not get media status playback information at the top of your activity and a few of the buttons will not work as expected, mainly the play button. Turning this to off fixes the problem.
Support request. Can you please look into this new player as i suspect at some point it will be automatically switched to ON as default on a future plex version upgrade and as of right now your integration with it is broken.
