I have filled the App Information with the our server Sandbox Server URL,

We followed the documentation below:

Answer 1

I think WWDC22 feature Request a Test Notification may help you.

ref: https://developer.apple.com/documentation/appstoreserverapi/request_a_test_notification?changes=_2

This feat request Apple to send a Test notification to your link. If you didn't receive, it may be a link error or App Store bug.(To App Store Bug, resave in the App Store Page may help sometimes)
