Update your IOS 9 on Apple devices!!!!!

Had tons of issues and found out my IPad had IOS 9 but NOT latest version of 9. It caused the app to crash. All good now once updated. Really fun. My 10 year old son loves them. Watch the videos on setup with your son. Especially for the battle mode with 2 cars and one person (cpu mode). Also it did not work on my older Samsung Galaxy tablet.
