iphone - Can not see iAd in program?

Question

My app has just released on Appstore ( http://itunes.apple.com/us/app/i-shock/id383457769?mt=8) . It runs with an iAd banner but I can not see it when I download from Appstore to my device (of course, network is working).

The status in iAd Network is "Live: This app is receiving live ads.". iAd preferences was typed.

My original code is running well on device with a iAd test banner.

Did I make somethings wrong? Thanks.

Answer 1

A number of developers are noting that the fill rate is currently very low. Also note that they are only live in the US.

If it works correctly in test then it's probably okay. I believe the analytics available in iTunes Connect shows the number of requests as well as the number of fills and clicks.
