Java Exception When Setting Amazon as Target UnityIAP

Hi Guys,

I'm on Unity 5.6, have multi-dex enabled, and am running into the following exception when setting Amazon as the UnityIAP target platform:

Setting to regular Android platform removes the exception (but replaces it with AmazonAppStore related class not found issue).

Any ideas on why I'm encountering this and how to possibly resolve this?

Warm regards, Lee
