I just redeemed a code, the thank you message appears, and I exit to the home background. Then I find out nothing is downloading. I check if it is on my 2nd page...nope! I go back into my email to redeem the code again. It's already been used and I can't redeem again. I tried writing a review for the game and it says I don't own the app. Now what?
If you got the Thank You message you should be all set, go on your itunes from your computer and 'check for available downloads' If it starts downloading then check your idevice a few minutes later to see if it's on there.
