I have a non-consummable in-app purchase that I am trying to submit for review. One of the requirements is a screenshot. I have tried uploading multiple screenshots of multiple sizes, all drawn from the documentation, but every one of them is rejected as the wrong size. The screenshots are coming straight out of the simulator, and I have verified that the dimensions match those in the documentation.
What else can I do to move this along so I can submit my in-app purchase and my app?
