So the solution is to simply ignore LAT and just try production? :-)

The issue happening turned out to be from Amazon LAT not working saying "An error occurred while processing your purchase" -> An error occurred while attempting to purchase this item please try again."

When I uploaded same code to production it worked!

Hi there,

It sounds like a configuration problem, possibly ProGuard or another code obfuscator (such as the new R8 in the latest Android Studio) interfering and stripping parts of your code as you export your app for release.

To test that, please either disable ProGuard / R8 before you upload the next beta version to Live App Testing, or configure it to exclude / ignore certain classes, and see if IAP works for you. For that, please see this article on how to configure ProGuard for Amazon IAP: https://developer.amazon.com/docs/in-app-purchasing/iap-obfuscate-the-code.html -- thanks!
