Problem when first used. – Sight Words Flashcard - 1000 words for kids in preschool, pre-k, kindergarten and grade school Review

Bought the app a tried to adding three users. When I tap "profile setup" it kicks me out. I scrolled Down to set 10 and it kicks me out. This is the worst app I've bought to date. This so disappointing.
