Admob doesn't show my app. How to solve this problem?

Question

iOS

I have created an app for iOS. At the final stage of development, I added the Google Mobile SDK to it to display ads. It worked fine with test IDs. Then I replaced them with real IDs and that worked too. I have published my app in the app store. Now I have opened the settings of this application in admob. In the app info, I want to populate the app store cell. I clicked the add button. And typed in the name of my application.
It didn't work. Then, I tried to enter the app id and developer name. This didn't work either. How can I solve this problem?
PS My app was published over a month ago.
