User Profile

When a user upgrades or downgrades their auto-renewable subscriptions via the "Manage Subscriptions" URL, how is the application notified of this? It doesn't appear that any kind of transaction is processed on the transaction queue, so how is the application supposed to know that something has changed? When does the receipt get updated with this information?If a user upgrades from subscription A to subscription B, how does the app know this has occurred? If there was an SKPaymentTransaction in the app, we're not seeing it. Since there is no sandbox support for this scenario, I have no idea how to handle it.

Has anyone had success with receiving autorenewing subscripton notifications via the Subscription Status URL in iTunesConnect yet?I've set one up to do nothing but log incoming events from the App Store. However, the App Information page where you enter it says "This information is used for all platforms of this app. Any changes will be released with your next app version" and I of course have not pushed out a new version of the app just to test this server-to-server communication feature.Not sure how long I should expect to wait before seeing something come in from the App Store.... or how to debug the problem should nothing ever show up.
