iAds not showing in released app

I am using iAds with my app that was released on the App Store earlier today. In the development build, the ads show properly but they do not appear at all in the released version. Does iAds need to process the app being released or is this a problem with my iAds contract or code? I am using the latest official build of Corona and yes, I was connected to wi-fi when I tested the released version. Any help is greatly appreciated.

They take a few days to appear in the live app. It’s normal behavior.
