I’ve been battling with App Review for a few weeks now. After fixing everything else, it’s come down to the In App Purchases (IAP). I’ve been able to run and test the IAP with Xcode and TestFlight, but once I submit to app review, they say this:
“We have begun the review of your in-app purchases but aren't able to continue because your submitted in-app purchases indicate a change of business model for your app.
Specifically, your existing business model has changed to include a consumable in-app purchase business model type.
Therefore, we need to verify the implementation of your submitted in-app purchases in the app to ensure your app, and its in-app purchases, are in compliance with the App Review Guidelines.
Next Steps
In order to approve your your new in-app purchase business model, we have to verify the purchasability of the items being sold. Please upload a new binary and make sure that your new in-app purchase products are available for purchase at the time of review.”
