What is going on with the iAd network? My iAd supported app has been on the store for 4 days now and I'm seeing some very troubling things. My fill rate is only about 35%, meaning that 60+% of the time someone opens my app no ad gets delivered to them even though they have an internet question. A friend of mine several states away told me that they downloaded my app and no matter what they do they can't get an ad to show up. Not surprising given what the iAd Network page is telling me in iTunesconnect. Whats worse is my fill rate is in an exponential decline. Over 4 days it has gone - 50% 47% 22% 11% It almost seems like a ploy from Apple to get developers to convert their apps to "free" versions, require that they "hide" the ads when they're not being displayed and then only fill 30% of the requests for Ads.
