Game freezing when connected to Xbox Live-account

When logged in to the Xbox-live account in Minecraft on ipad it freeze when trying to load a World. I'f i logg out from the account it can open the Worlds normally.

 

Same thing when visiting the minecraft store. If i log into the account it keeps loading all small windows and ask for the internet Connection. In this state it doesn't load the coin-amount either. But if I visit the store without beeing logged in to my account I can se all the things possible to buy.

 

All this problems started with the lastest update of Minecraft.

 

I've tried it on different Ipads and I have reinstalled the game but the problem is still there.
