I was able to fix the issue by changing the base price currency of the product from USD to EURO. Why? I dont know! It was always USD for my previous products on previous apps as well, what changed? I dont know!

I am also having the same problem. Subscriptions products are not arriving. Non-consumable in-app purchases arriving only when they are "Ready for Review" state but i am not able to complete a purchase, and when i try to complete a purchase i get; Payment completed with error: Error Domain=ASDServerErrorDomain Code=3504 "This item cannot be found." UserInfo={NSLocalizedFailureReason=This item cannot be found., AMSServerErrorCode=3504, client-environment-type=Sandbox, storefront-country-code=USA}
