Fun but constant crashes

I love this game and find it addicting, but it crashes constantly. Its very frustrating. Ive found wild animals, pay to rescue them, and then the game crashes upon loading to return to the zoo. So instead of spending ~60 seconds finding one animal, I have to re-find it multiple times, relaunching the game every time, wasting coins each time. I quit the game. I was hoping with the newest update it would be improved, but it hasnt. It crashes while feeding, finding, importing. Very annoying as I would love to play this for hours, but the crashes prohibit that. I am using an iPhone 7 with plenty of memory available.
