Mutated Plant-Super Skill

I’ve been having a lot of fun playing this game but I crash every time I beat a level and I don’t even get the rewards from it. I also have been playing and the zombies get stuck at the back of the screen and the plants can’t hit them not even bob can hit them, l think this happens when dragon scroll fan blows away a zombie that is eating a plant. So please, get this fixed thank you.

I honestly like it, but there needs to be a fix because whenever I complete some levels just kicks me out of the game and I don’t even get my rewards and whenever you complete a level another level is already open to play

Sometimes when I’m in a level of the zombies are stuck at the very side of the screen and none of the plants can hit the zombies, not even Bob. and they also don’t move when you’re stuck in at the side of the screen. Also, the game crashes at random times. Please get this fixed. Thank you
