We recently released an app for the Amazon app store. Our in app purchases seem to be failing. (The purchase works successfully using the sandbox (SDK Tester), but the live app downloaded from the app store fails.) Here's what happens: The user, in our app, selects "buy", our app calls the "initiatePurchaseRequest" in the amazon sdk. Then, the Amazon Appstore window pops up asking the user to press the Amazon Appstore popup window "buy" button and confirm the price. At this point control has been passed to the Amazon Appstore activity. The user presses the Amazon Appstore popup window "buy" button and the Amazon Appstore notifies the user that it is "purchasing...". Meanwhile, the user receives an email stating that the transaction went through and they were charged. Back in the Amazon Appstore popup window, it continues to say "purchasing..." for aproximately 1/2 hour, then notifies the user that the purchase was successful. No receipt data is received by our app at this time or any time before, and the "Amazon Mobile App Distribution" Dashboard shows 0 in-app purchases for this app. There seems to be something wrong with in-app purchasing in the Amazon Appstore activity.
