So I go to change my GT and it says loading and then it says an error...i mean wtf it says it every time i try. But i go on another account and it lets me access it. This type of error also happens when I try to add a credit card to my 2nd account...
Did it give you an error and a status code? Cuz that happened to me with all my accounts and like i called xbox and tried sorting it all out and they couldnt help, and i waited and like a week ago it started letting me pass the error.
