Home Screen Glitch

There is a glitch on the home screen. After the game loads, I get pink and black pattern squares all over the home screen and the settings screen is all pink. It is also telling me to unlock the full game, which I ha e already done, and if I click it I get taken to the Google play store and am told to uninstall or open the game.

I have already uninstalled and reinstalled the game multiple times. The pink and black squares are still there. I cannot do anything to fix this so I need help. 

HELP ME FIX IT PLEASE so I can play again!!!
