Remember to Enable iAd for New iOS Apps After Uploading Binary
You can enable iAd network ONLY when your app is in an editable state. That is after uploading binary and before being approved.
If not, you can’t.
I am not sure how many developers forgot to enable iAd. But I am one. And I blatantly forgot to enable 1 app for over a year.. (I also use Admob, Mopub, MMedia, etc)
Why can’t we just flick the switch?
