I have verified that the Paid Apps Agreement, bank account details, tax forms, compliance and other related information are all valid. I created two IAP products using identical configurations. One can be purchased normally, while the other returns an invalid product error. Moreover, any newly created products still trigger the same invalid product error. I have attempted multiple troubleshooting steps: clearing purchase records for sandbox testers, creating new sandbox accounts, uninstalling the app, and restarting devices. Unfortunately, I have still not identified the root cause. I hope to receive additional troubleshooting guidance.
Help: Invalid In-App Purchase Products
Update: After waiting roughly more than ten hours, a new IAP product I created last night became available. However, the second product I created still returns an invalid product error. Has anyone encountered this inconsistent issue? I am quite concerned that this problem will persist after the app goes live in production. This strange behavior is confusing to us.
