Amazon Mobile Ads not working

Question

I have implemented Amazon Mobile Ads in accordance with this guide: https://developer.amazon.com/public/apis/earn/mobile-ads/docs/quick-start

But I am having trouble getting ads displayed, and it looks as if my app is somehow rejected by Amazon ad server:

A few info that may be relevant:

1. The SDK is the most recent one (downloaded from https://developer.amazon.com/public/apis/earn/mobile-ads)
2. Most of the code are the same as example project (FloatingAdActivity.java)
3. If I change app key to the same as example project ("sample-app-v1_pub-2") it works
4. The app is registered but not yet published
5. I am not based in US

What should I change to make my app able to display Amazon Ads?

Answer 1

Turned out the problem is on Amazon's end, contacted them and got it fixed a day later.

The process was quite straight-forward: I used their developer contact portal: https://developer.amazon.com/help/contact-us.html, selected "Mobile ads General" as the Subject, and the content of my original question above as the Message. They were then able to determine the issue and fixed it.
