Will not run half the screen is cut off

Will not run half the screen is cut off, and in the main menu when I click profile, nothing happens, and I have to exit the game. I have an iPhone 6 plus with the latest OS. I dont think theyve updated the game in a long time. Im not sure why its still available for purchase.
