I recently updated my Developer membership. My new contract went into effect May 19th. Last week I went in and browsed my iAd earnings, and noticed that all of my iAd apps are "Red" and not receiving ads. After expanding the details to find out why, the iAd module tells me that my iAd contract has expired. However, the Contracts, Banking and Tax module reports that everything is OK, and my iAd contract will be in effect until May 19, 2013.
Incidentally, my last day of revenue was May 19th of this year.
I called Apple Support, have had a follow up phone call where it was requested I submit screenshots, but I haven't heard anything back. Has anyone else experienced this?
