Hello, I sent my Android app Cartoon Compass to Google “Designed for families” and was rejected due to a policy violation.This is their message:

We found the following issue(s) with your app. Ads and Monetization: Ad Content
The ad content in your app does not comply with Families Policy Requirements.

  • Your app contains an ad for gambling

Here is the screenshot they attached:

And this is my Ads settings (to NOT show ads rated +5):

Your AGE LIMT SETTINGS IS NOT WORKING CORRECTLY!.

Hello, I am sorry you are experiencing this issue. I am investigating now. Can you please create a ticket by emailing unityads-support@unity3d.com with the information included in your post?

Hi, I’m also experiencing lots of gambling related ads resulting in games being rejected from the Play store. I’ll make a ticket also!

Done.
