Great App but doesn’t work with iOS 11 – GeoBee Challenge Review

This app is one of the best apps to study for geography bee. It helped me get to 2nd place in my school a while ago yet I’m trying to study for the next geo bee and the app won’t work with iOS 11 and all I have is iOS 11. Please update the app, National Geographic developers.
