Hi, We have implemented Version 2 App Store Server Notifications on our server. We updated the "App Information" page in App Store Connect to send Version 2 App Store server notifications to a new endpoint. We are mainly receiving Version 2 notifications at this time. However, we are still receiving Version 1 notifications several days later. Is it expected that Version 1 notifications will still be sent even after we have chosen Version 2 notifications?  STEPS TO REPRODUCE Last year Implement Version 1 notifications endpoint at https://oursite.com/appStoreV1 Update "App Store Server Notifications" section to use https://oursite.com/appStoreV1 Verify notifications are processed correctly. This year Implement Version 2 notifications endpoint at https://oursite.com/appStoreV2 Test using our Sandbox configuration by changing the "App Store Server Notifications" section "Sandbox Server URL" to "Version 2 Notifications" and change the endpoint to https://oursite.com/appStoreV2 Verify Version 2 Notifications in Sandbox are processed correctly. Update "App Store Server Notifications" section "Production Server URL" to "Version 2 Notifications" and change the endpoint to https://oursite.com/appStoreV2 EXPECTED BEHAVIOR We no longer receive Version 1 Notifications at all -- to either our old https://oursite.com/appStoreV1 endpoint or our new https://oursite.com/appStoreV2 endpoint. ACTUAL BEHAVIOR 3 days after changing our configuration: Mostly receive Version 2 Notifications We have received 25 Version 1 notifications to our new endpoint as of writing We continue to receive Version 1 notifications to our old endpoint
