I can’t get in – Britney Spears: American Dream Review

So I have an iPhone 7 and it says it’s compatible with this phone so I downloaded it and every time I try to play the game it won’t let me in and goes back to my home screen please fix this now cuz this is sad and maybe if it got fixed you’d get a better review
