In-app Purchase Not working In Production for iOS

Hi. I got my three apps approved by Apple. Only one of them has in-app purchase working in Production. The other two apps with in-app purchase were not able to fetch product details. However, they are working fine using Sandbox. All of them have the same process of submitting to appstore. One app works fine both in Sandbox and Production. I only have problem with the two apps. All of the in-app purchase are non-consumable. Any idea? TIA.

I hope someone can help.

Did you find the solution, I have the same issue on my app :frowning:
