My wife and I both purchased Grounded, and while I had no problem logging in, she has had an issue.
XBox account works just fine everywhere else, logs in correctly, only with Grounded is there a problem after having a failed login attempt due to incorrect password entry.
Now, every time she tries to log in, she gets an error about 'There is a problem with your Xbox account." No chance to re log in or change accounts so that she can attempt to log in again.
We have tried disabling cloud saves and reinstalling the game.
What can we do?
