(in response to H2OSkier)
Is there any way to test cancellation and subscription downgrades?
For cancellations, there is no good means to do so. The cancellation_date field is only set when Apple Care refunds a non-consumable or auto-renewing subscriptiuon purchase. There's no simulation for this in the sandbox environment. Id submit an enhancement request for iTunesConnect to have the iTunes Store server in the sandbox have a means to simulate this in the applicationREceipt
For subscription change, run two copies of the app. In one, make the purchase to different items in the subscription group. after the change, if the change becomes active, then launch the app on a second device and have it refresh the applicationReceipt and validate the receipt. The subscription change should be present.
The use of the second app will detect renewals made in the iTunes user subscription area as well. However one cannot use this method in the sandbox - another enhancement request.
When does a downgrade show in the receipt?
It was my experience that all changes occurred immediatelty. If your app offers all grouped auto-renewing subscriptions, try purchasing each one before the subscription expires. As I recall, there is an alert to indicate that the change is effective immediatelty.
One other thing, if the applicationReceipt contains an auto-renewing subscription item in the in_app array, then you can manually validate that one applicationReceipt after the purchase of a different subscription in the group - and the JSON results should show the change. This receipt update process only applies to auto-renewing subacriptions. If the first app is later used to make a non-consumable purchase, validating the original application_receipt will not show the non-consumable purchase.
>Oh, and any timeline for the documentation to be revised ;-)?
This would be for a Developer Publications writer to respond to. I work in DTS. I guess I could write a Tech Note - hmm.
