ios Started freezing in game yesterday 17JAN20.  This became progressively worse to the point that the game now freezes when loading.  Observations:

Game only freezes when connected to wifi.

Game will load and login to microsoft account using cellular data.

Problem appears to be related to logging into microsoft account.  Cannot say what the difference would be between using wifi and cellular.

To test shutoff wifi and the game will launch properly.  Close game and turn wifi back on, game will not load. 

Turn wifi off launch game and logout of microsoft account.  Shut down game.  Turn wifi back on and game will load.  Will crash once microsoft account has logged back in.
