Why my server can't receive non-consumable in-app-purchase notification?

I set both production and sandbox App Store Notification server.

In sandbox, my server can receive all kinds of app store notification, including subscription and non-consumable in-app-purchase.

But in production, my server only receive subscription notification.

I can see some non-consumable in-app-purchase done in log, but the server didn't receive expected notification.

Anyone know why?

I really need the notification cause I need to know who made refund.

Why my server can't receive non-consumable in-app-purchase notification?
