The problem is the parents not reporting the infraction. At least WRT google play app store, they can be brutal toward apps with ads with wrong content criteria, see the link discussing your situation https://play.google.com/about/monetization-ads/ads/inappropriate/ https://play.google.com/about/monetization-ads/ads/inappropr... with a side dish of https://play.google.com/about/monetization-ads/ads/interfering/ https://play.google.com/about/monetization-ads/ads/interferi... Presumably whatever the amazon devices use for an app store (google play, I donno) has similar draconian policies to enforce IF the problem is ever reported. Unfortunately I've had to set up ads from the developer side and the Google UI is not bad, but nothing's perfect, so in a world of a million apps its entirely possible the dev accidentally screwed up age criteria rather than was willfully antagonistic; but if parents don't report the problem to the dev or appstore there is little hope of improvement either way. If you can get the attention of Google's automated AI eye of sauron in policy enforcement, I assure you they are remorseless, draconian, and merciless. The difficult part is getting their attention. My kids have learned from youtube how to side load cracked and modified apps such as minecraft on their devices downloaded from mysterious and unsavory websites, which promptly messes everything on the system up, such that its possible the app dev and Google have nothing to do with your situation.
