Amazon IAP works in sandbox mode, but not in real life

Question

I'm trying to enable Amazon IAP using Amazon's Unity plugin for IAP v1.0. The game uses Prime31 for Android and iOS stores, I'm implementing the Amazon IAP side-by-side with that. The purchase works fine with Amazon's SDK Tester (which provides a sandbox), but when I try it on the released game it fails. I don't have a Kindle Fire or such, but I install the game using the Amazon Store App onto my Android phone. Here is relevant logcat:

It's coming from the guts of the Amazon IAPplugin parts from Unity. I call AmazonIAP.initiateItemDataRequest in the beginning of the game, with the list of the SKUs of my inventory. Seems like it returns fine. What else can I do? Any help is appreciated.

A fellow Unity developer advised to hack Amazon IAP 2.0 into the IAP 1.0 plugin. But it's not that easy, I'd have to replace the encompassed jar, rewrite the bindings...

Refresh in-app-purchasing-1.0.3.jar in the guts of the Unity plugin supplied by Amazon with in-app-purchasing-1.0.20.jar. Besides that I added a call to initiateGetUserIdRequest, not sure how much that matters: initiateItemDataRequest worked before without that. So one of these changes or both of them made the headache go away. No I have 3 calls in the Unity game/app:

AmazonIAP.initiateItemDataRequest (QueryInventory ()); // QueryInventory is my own function, I know my inventory right now, I don't build it dynamically.
AmazonIAP.initiateGetUserIdRequest (); // Still during IAP initialization
AmazonIAP.initiatePurchaseRequest(itemID); // itemId is the SKU string

I utilize the AmazonIAPEventListener.cs supplied by the IAP plugin almost as it is, I just needed to wire in the increase of the game's virtual currency:

 void purchaseSuccessfulEvent( AmazonReceipt receipt ) {
     AmazonIAP.Log("purchaseSuccessfulEvent: " + receipt );
     PlayerCredits.AddPlayerCredits (receipt.sku);
 }

Hope this helps others!

It's crazy that I can only test if the real IAP works well only if I publish the game and in production. It always worked fine with the Tester sandbox.
