Thank you so much for posting the step-by-step solution! It solved the exact same issue for me. My app version was stuck in the previous submission, and the IAP remained in a separate draft. Following your instructions, I removed version 1.0.71 from the old submission and then successfully submitted the app version and IAP together. The new submission is now marked as “Waiting for Review”. I really appreciate you taking the time to share the solution. It saved me a lot of frustration! Kind regards, Joost

Hi, I'm experiencing almost exactly the same issue with my first IAP. Did you manage to resolve it? If so, how? I’ve described my situation here: https://www.reddit.com/user/Traditional_Cat4833/comments/1x2qjv7/unable_to_submit_my_first_inapp_purchase_for/ Any insight would be greatly appreciated. Thanks! Joost
