Downloaded yesterday, beat first scenario, the next and all the other say go to the store to buy....but the store button does not work. Can't find any way to purchase either in-app or out. Kind of sad because I really like the game...working on an Ipad, version 10.3.3 (14G60) model me277ll/a and plenty of available space (20gb)

Just checking for the basics. Are you logged on the Game Center in the settings?

Because logging in the Game Center is needed for purhaces and storing the achievements.
