Horns dont work

I think I would like this app if the goal horns and end of period horns would work but for some reason none of them work. Every time I try, the place where you pick your goal horns says tap to unlock and when I tap it brings me to the App Store and says cannot connect to iTunes Store when I have full wifi. Please fix this.
