Game never makes it past loading screen

Unknown

I recently updated to lollipop and now the game won't load fully. It makes it past the initial loading screen (the one with a few characters on it) then the screen goes black. I've tried to get the game to load a few times over the past few days and it does so very sporadically. Any advice as to what is causing this issue?

My Android tablet has just updated to lollipop 5.1 and now can't even get to the loading screen.
