As far as my users go, is there a difference between using version 2 or version 3 of in-app billing in Google Play? Right now I am in the console, thinking I am using version 3. But I see three options: managed, unmanaged, subscription. However, version 3 is supposed to only have two options: managed and subscription.
My API, I think, is using version 3, which is what I want. But the console is confusing me. So how do I make sure I am indeed using version 3?
The reason this is not so simple is because in version 3, managed goods can be re-purchased once consumed; whereas in version 2, managed goods are once in a lifetime. I am hoping to get answers from people who have actually successfully used version 3; so I won't go into discussion of unmanaged goods. Thanks.
In-App items are shared between version 2 and version 3 (i.e., a managed item can be purchased via the v2 or v3 methods). If you'd like to use version 3 (and you should, 100% of the time), then you'd want to make sure you are following the Implementing In-App Billing V3 Guide.
