Those of you that waited patiently are in for a treat today. The regular Plex app has been updated to include Chromecast support for everyone. The Chromecast support also is capable of casting your music and photos from your Plex server too. As with all updates, it also includes fixes around remote controlling the Chromecast and lots of bug fixes.
Be sure to go update the Plex app if you aren’t a Plex Pass member and check it out on your Chromecast. If you are totally clueless, you should head over to Plex.tv and take a quick read. It could very well be worth your time and the cost of the $4.99 app.
