Could you please provide us some more informations? Where is the game not loading? Do you have the newest update of the current App? What kind of mobile device do you need? Is it the first time?
I just did the update. The app Version is 1.9.0
it's on the loading screen. All I see is the arrow turning I circles like it's thinking orsynchronizing. I get lucky if I make it in the game. But then it's just slow and laggy.
Liam said there were technical issues with the update of 1.10. Maybe that's the problem. Maybe it was another try to update the game. Just wait and we will see.
