Undergoing maintenance

I get it after my iPad tries to connect but can't usually to weak cell signal or no avail wifi. It is a BS message and I recommend exiting the game, double tapping the home button, hold and delete the simpsons logo in the new menu popped up from the double tap of the home button. This completely closes the game out and makes you re sync with the game. Check your connectivity to make sure you really are connected before trying this.
