Update casting a stream (Chromecast)

Recently, you updated the Twitch Chromecast App with the actual design, improving vods, etc...

But i use the "cast to" with the Twitch mobile app, an it carries me to the old design from the Chromecast App, and without chat (we don't have an option to put the chat in the Casting format).

So please, update the Casting format to the actual Chromecast App Update.
Thanks.
