My screen has been black with a small loading icon in the corner for about an hour. It was working fine earlier today, im not getting any errors just a whole lot of nothing. I've reset my connection, cycled the power on my XB1 and modem. This happened to me last week then suddenly worked out of no where with a prompt asking me to download an update. Does any one know how i can fix this?? or better yet whats causing this?
