Is this by design or is it a bug?
We are looking into this now 
Thank you Nitro Glitter. It is the only way i can record my youtube videos with a decent quality at the moment until i can get an Elgato.
Also cannot stream using Twitch on the xbox one
Thank you for letting us know. We have identified the issue are working on a fix.
Great to hear thank you very much let us know once it is fixed please so i can get to recording my video for my youtube channel.
I streamed on demo mode, with no problem. Follow my next reply, and get back to me
I streamed F7 on mixer no problem. Just make sure to go on your mixer channel, go to broadcast, and select the game,form the drop down menu, you are streaming. And i am sure you already know you need stream key to stream on mixer.
