Unusable app – Khan Academy Review

This app is unusable. When I’m entering the answer there are two menus from which to slide back and forth to select symbols/numbers from, however whenever you slide from one menu to the other you HAVE to hit a symbol while trying to slide it and then you cannot delete that symbol without losing the symbol you’re trying to get. I’ve wasted so much time trying to figure out how to fix this. Until this is fixed don’t waste your time...
