I have verified that my sandbox endpoint works for App Store Server Notifications (V2), by requesting a Test Notification.
When I issue a beginRefundRequest in my app for a Sandbox account, my backend does not receive a request. According to the docs this should work in Sandbox too: https://developer.apple.com/documentation/storekit/transaction/testing_refund_requests
What could possible be missing if the TEST notification works, but the REFUND notification doesn't?
