Anyone that uses the Youtube app on the Xbox One will know that it automatically signs you in when you enter the room as it uses facial recognition via the Kinect , which is a really handy feature. Up until someone else walks into the room that is. Lets imagine for a moment that you have just been signed into Youtube and you are now watching Team XPG's latest mods when you're brother walks in to borrow one of you're games. The Kinect will now recognise you're brother and kick you back to the Youtube homepage whilst signing him in! This is only a minor glitch and will hopefully be fixed in an update since quite a few people have experienced the same issue and reported it to Microsoft.
I know why it gives me a error. I had no xbox live so I added a code any tried again and it worked!! The error I had was something wrong try again later.
