title: In App Purchase not working after it has been approved
body: <p>as the title says it's a question about my new released app which included one In App Purchase. When I tested the Purchase on the app which I downloaded from AppStore I got no Alert that the Purchase was successful. First a alert View with "Would you like to buy... for 0.99$" came up, I proceeded with Buy. Then I had to type in my mail and password and clicked continue. Then nothing. No Alert that it was successful or something. I also programmed a Indicator that stopped after the second Alert View after few seconds.</p>
  
  <p>I hope it's Apple fault and hopefully it's only a delay.</p>
  
  <p>What do you think?</p>
  
  <p>Thanks in advance </p>
