So I'm having difficulty getting Alexa to play Plex on my Shield device. I've tried multiple times to deregister and register the skill set on the Alexa and then re link my Shield device to my Plex account, but everytime Alexa recognizes the server and the Shield and then says it's playing the content, but nothing happens. I'm wondering if anyone has found a solution to this problem.
Update, it appears that the Plex skill from Alexa does trigger the Shield (i.e. if the Shield is asleep it will wake the Shield), but it just won't launch Plex or play the selected content.
