I know some people have been posting about not being able to get in to the beta on Xbox One. I think i might know why. On the Beta version of the game it is marked as "Pre-ordered" in the bottom left corner of the game icon. I think that somehow Xbox marked the beta as something that needs to wait for the launch date, so when you click the game icon it gives you the same screen it does when you click the game icon.
It just sends you back to the store and tells you your to early.
So, Rare needs to get the pre-order tag removed from the game.
