Farm Heroes Saga is not launching since last update

Finished level 721 a few days ago. Beat Rancid with 1 move left. The game then ended as the program closed out to the home screen. Each attempt to reload the game ends with the game closing out to the home screen. Double clicking the IPad mini home screen shows the game open in the background at the same screen showing Rancid has won. When bringing the screen with Rancid forward the game appears to try to load but fails back to the home screen. Any ideas to fix this?  Thanks
