We are utilizing the App Store's server-to-server notification feature. Upon receiving a notification on our server, is there a specific deadline or time limit for responding back to the App Store? We just skimmed through the below documentation https://developer.apple.com/documentation/appstoreservernotifications/responding_to_app_store_server_notifications In this doc we could only see the responses that app store is expecting us to send back but no any information regarding acknowledgment time for a request

I have implemented IAP to test locally and tested it out in virtual device. Is it possible to test IAP using apple store connect on a virtual device or should I use a real device for that testing ?? I have gone through various documents but there are no any document addressing this issue 😞
