Amazon IAP store.init black screen

I’ve integrated the Amazon IAP API plugin into my game. Everything works fine while I use SDK Tester. When I uninstall the SDK tester, a black screen is displayed and based on the debug statements that I’ve placed, the store.init call is causing the game not to run. I do have the application live and 2 in app products also live. Do I have to have this version published and downloaded through the Amazon Appstore before it starts to work, or am I supposed to be able to run it without downloading from the Amazon Appstore. In other words, would publishing this version fix this issue? Maybe Amazon modifies the package that causes this store.init function to succeed.
 

Thank you very much!
