We recently submitted an update to Amazon for one of our apps and noticed as part of the reply that Amazon is suggesting we upgrade to their v2.0 IAP:
"We’ve determined that your app uses an older version of the IAP SDK. This may result in inconsistent behavior of IAP on the customer’s device. We would suggest that you update your code to IAP v2.0. You may download the latest SDK from https://developer.amazon.com/public/resources/development-tools/sdk."
Does Corona have any plans to update the Amazon Plugin to v2.0?
The updated API has been out at least a year and I am concerned about being caught short if Amazon removes support for the older API. With a number of apps to support, implementing the change, testing and updating can take some time.
