Hi,
recently I created some campaign lines in the iAd workbench using templates. By choosing itunes as the destination i could set a CPA goal together with budget, daily spend goal and CPC bid. A couple of days ago i tried to create an ad (a simple banner with itunes as target) in the iAd Producer App on the Mac. After uploading I wanted to create an new campaign line and use the Ad from iAd producer. But as soon i choose "Expanded Ad" as destination, the field for CPA was gone.
And here is my question: Why is that?
Thanks in advance
