Issue with Notification Delivery to Server on Successful Transactions using react-native-iap

[NgoMinhNhi]

I'm integrating mathematical features into my application using the react-native-iap package. However, I'm encountering an issue where the server doesn't receive notifications from the App Store upon successful transactions. This problem persists both in development mode and with TestFlight testing.

However, when I utilize the @apple/app-store-server-library package to invoke the requestTestNotification function, the server receives notifications as expected. Additionally, using the getTransactionInfo function retrieves transaction information successfully.

I'm seeking assistance in resolving this notification delivery issue to ensure that the server receives notifications from the App Store upon successful transactions. Any insights or guidance on troubleshooting this problem would be greatly appreciated.
