Interstitial AD problem.. ( zero impression )

[Edward K.]

Hi, guys.

I have a question.

I applied  Interstitial AD  in my iOS app, a few days ago.

And the updated app was released on the app store yesterday.

But, as follows, 

the impression is zero.

[AdMob Report]

                      request   impression

2014/04/11             91                  0 2014/04/12             95                  0

When I tested it on iOS Simulator, the Interstitial AD was presented well.

(The banner AD has been applied on this app too, several months ago, and banner AD has no problem at all. )

Do I need another process for  Interstitial AD ?

Unlike banner AD, I heard that ,  the developer need to proper qualification for Interstitial AD.

Should I wait until Google( AdMob )  send an email to me?

Does google (AdMob) even realize that I applied the Interstitial AD in my app?

Thank you for your help in advance.

Hi Edward,

You don't need special qualifications in order to serve an interstitial ad. My first guess is that you're not using the correct kind of Ad Unit ID. Can you make sure that you're using an interstitial id instead of a banner id? You set this up in the interface.

Hope this helps.
