iphone in-app purchases not working after rejection

I recently had an issue with my in-app purchases, so had them rejected. I found that upon creati开发者_开发问答ng new ones and approving them, I am getting no products back from my SKProductsRequest. Do new in-app purchases require some delay to be updated on their servers or is there some common reason that they stop working when an app is rejected?

It turned out my paid applications contract wasn't filled out, so the server was silently rejecting any product requests.
