iAd fillrate is 0 after 4k requests

Question

We launched an app on friday that uses iAds (full screen as well as banners). The dev version shows that iAds are working and itunes connect states that our app is live and receiving ads - but so far there were about 4k requests but fill is still 0.

Is this normal? How can I exclude that there is any technical problem preventing the app to receive ads?

edit: the app is in english and was launched globally (most of the 4k requrests originate from the us)

Answer 1

Possibly not whats happening to you, but I can tell you if the iAd team stops your app receiving Ads (for instance because its aimed at children) then there is no indication and you will see exactly what you are seeing.
