Hello - As a next step, please try resubmitting the app update that supports the In-App Purchase functionality. In the submission notes, provide details about the related IAP products that were previously submitted (including specifying the Product IDs, etc.) - to make it clear to App Review that you need the app update and the previously submitted IAP products to be reviewed together, as part of your initial release of IAP support in the app. Please let us know if you need any further assistance. Thank you.
