App details in app store search results?

So I just picked up an Ipad Air, which is my first ios product ever, and I feeling like an ****** idiot for asking this, but the app store is driving me nuts. If I search for something in store, I get a long list of different matches and I can see all these tiles with pictures, names and prices for all the apps that match my search. Great. But what if I want to go to the individual store pages for these apps and read more about them, what do I do? Tapping them doesn't work. Nothing I have tried works.

I assume I must be missing something here. Surely I can't be expected to pay for and download apps based on their names and thumbnail pics?

 

A reboot apparently fixed my problem.
