The official Xbox app for Windows 10 devices got updated recently in Windows Store. You can now control your party’s chat volume, and choose a specific audio device. With this update, you can watch game broadcasts in clubs. Clubs are gamer-created and managed groups that can help you meet people and grow communities of gamers who love the same things you do.
This update also brings support for Co-stream with friends. Mixer has a built-in cooperative streaming experience in which up to 4 streamers can combine their streams into a single viewer experience. Basically, multiple channel streams can be displayed on a single Mixer page. Once you get an invite, just accept to go to Mixer.com and co-stream.
Most importantly, for White Walker fans, the app now also supports the Light Theme.
