Hi Gary, thank you for your reply!
Unfortunately "trusting" the Google Play API is exactly what I'm having a problem with in this case: I'm convinced that Problem 2 in my original post is a fundamental design flaw in the API. And I still haven't found a good way to work around it (other than adding and maintaining multiple versions of each consumable SKU into the Play Store (yuck!)). I'm pretty sure that that failure mode is exactly the reason why every other app store (including Google Play in the past!) does make the distinction between consumable and non-consumable items. The practical difference between the two being that ownership for consumable items is tracked on a per-device level while ownership for non-consumable items is tracked globally across all devices for a given user. Removing this distinction from the API, the way I understand it, was a mistake that Google made and Problem 2 is how this mistake plays out in the real world... What I'm really trying to do is find some way to get a hold of someone at the relevant Google team about this. I've tried StackOverflow, here, and messaging them directly on Hangouts. I just cannot get a hold of anyone. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
