I’m testing auto-renewable subscription purchases in the sandbox environment. When I buy a subscription package using a sandbox test user, I don’t receive any Apple Server Notifications from the sandbox. However, when I use the Request Test Notification option in App Store Connect, the notification is received successfully.
My sandbox server notification URL is configured correctly and publicly accessible. I also call finishTransaction() after purchase.
It looks like sandbox purchase notifications are not being sent, even though the test notification works fine.
