We are using Firebase Cloud Functions as a backend. We created a function to handle App Store Server Notifications, however, it is never called.
It is possible to call it manually in a web browser and the same https URL is defined for the app on AppStore Connect.
We are making purchases in a sandbox environment.
Any ideas? Is the service down?
Looks like in my app webhooks stopped coming again since the previous time: https://developer.apple.com/forums/thread/680354
Still no solution?
I also have trouble in same issue now. In sandbox env, renew event isn't happened anymore. I checked even latest receipt isn't refreshed through receipt validation in the env. The event was working until yesterday.
I also have trouble with the same issue now in sandbox env. Is this issue fixed now?
After two days, it started working again.
