A lot of problems
So I downloaded this app for my daughter and paid the £0.89p to unlock all categories. Quickly gave up on this app as on 3 of the first 10 questions my daughter answered it said that the correct answer was wrong when selected. Proceeded to tell her what the correct answer was (the answer she tapped). She got very confused and frustrated with it. When I had a look and tried - In fact it said all the answers were wrong - refund requested
