Crashing after update (IOS)

I have noticed the game shows loading screen then immediately exits afterwards. I have deleted and reinstalled the game probably 3 times, and it works every single time, but then after not playing for a while it crashes again. Thought it might be a solution, but obviously there is a problem somewhere else. Also, experienced it on both my IOS devices with separate accounts.

First thing that I always do is turn of Sounds in settings and moving the sliders to the zero position. Other than that, I log into the webstore and then just play as otherwise. Not sure where the glitch is coming in, but please fix this ASAP!
