一款集成了iAd及AdMob的app，在iTunes Connect中点击Transfer App，显示“If you have iAd related account information that is pending setup or pending an update, you can only transfer your app once the setup or update has been completed.”
检查“Contracts, Tax, and Banking”，所有的contracts都是In Effect状态，包括iAd App Network。
发邮件问苹果，回答说“Please contact the recipient and have them confirm that all iAd contract information is up to date. They will not be able to accept your app transfer until this process has been completed.”。
但事实上此时还没有到填写recipient信息的那一步。再次咨询苹果，一直无音信。
求朋友们指点一下，非常感谢~
Apple的技术support终于发来回信：Thank you for your patience. You should now be able to transfer your apps. Please let us know if you encounter any further issues.
算是他们自己系统的bug吧。
