The whole productID and in app purchase system is pretty broken. You have to continuously create new productID’s if there are any issues with old ones, which leads to having to resubmit your app for approval.. so making a small Adjustment on the website to try and link your IAP’s properly = start approval process all over. But you can only have 1 IAP for that process.. sound alike you have gotten stuck somewhere in this circular hell. You probably need to just restart an entirely new project. There is far too much hidden data that Apple keeps from us. Undoubtedly something there is wrong, but h less they show it to us, there is no way to fix other then starting over :( Really is a dumb system.
