Hi,

Yes Mixer formerly beam is to shut down on July 22nd and merge to Facebook gaming. Before mixer they had Twitch in place. If you want to still stream off your console you can download the twitch app. Once downloaded you have to open the twitch app set up
your pre broadcast settings then hit broadcast and return to the game of your choice to stream.

Hello Cameron,

Thank you for posting on the Xbox forums. We understand that the aspect ratio of the game is changing when you start broadcasting on Mixer. There may be some

broadcast and capture settings that need to be changed before the game can be set to full screen. If changing the broadcast and capture settings does not resolve the issue, we suggest reaching out to the
Mixer support team. Be sure to let us know the results!

Hi ,

Just try to reset your account privicy settings and then set it on adult account and re-allow the streaming for it.

I tried that a few times last night, it didn't seem to help. Are there specific instructions on how to do this? Maybe i messed something up.
