ADBannerView fails to receive ad with error 'The operation couldn’t be completed. Ad inventory unavailable'

Question

I started to implement iAd into a new App yesterday. But getting the error from the question title since then. Anyone know how I can fix it?

I've read here that it might be Apples fault. But since that thread is pretty old and I couldn't find any discussion on the Apple Dev forums about it for the current time, I don't believe this is a general issue on Apples side in this case. Also the problem can't be that they don't currently have enough ads to show because that only matters in live ads.

Some further information:

I did enable iAd Networking in iTunes Connect for the app.

The app even appears in my iAd monetizing summary in iTunes Connect. Its 'Ad status' is set to 'Test ads' (with a yellow sign) but the 'Requests' count is 0.

Maybe you can change your fill rate in Settings.app. Set it to 100% if you want it to show up all the time.
