No problem but this is a common misunderstanding. You don't need to use Amazon ads in Amazon apps. I regularly take my Google Play APK (finished binary) with Admob ads embedded and submit it to the amazon app store. never had an issue and the funds arrive as expected.
There is no need to create a Google Play APK and an Amazon App APK - the same APK works on both, with Admob ads in both. The beauty of this is you create your app once, and it can go to both markets with no changes.
Good luck and feel free if you have other questions!
EDIT: Amazon ads are terrible, terrible, terrible, with low fill-rates and close to zero money return. One of my apps is on both platforms (GP and AMZ) and the GP revenue is 10x the AMZ revenue. The AMZ app is using Amazon ads.
