So maybe others can confirm this, but this has happened to a friend’s Xbox One and my Xbox One S. We would load up YouTube and then MCC right after and then the Xbox One turns off. Every SINGLE time without fail. This is incredibly frustrating and I am surprised more people don’t know about this. Any other game this does not happen. For example I know for a fact it does not happen with Evil Within 2 or Sunset Overdrive as I have used YouTube and went back to the games with no problem.
This is an issue with the Xbox Platform, not Halo. Quit YouTube entirely before loading something else.
