What is your app?

What is the error message? Post a screenshot of it.

What have Google told you to do in order to solve the problem?

What steps have you taken to solve the problem?

Mate remove startapp sdk use only native kodular ad components for the apps designed for children. Its gonna be ok.

Read the family policy it’s written there that which ad network you are able to use to comply with family policy and ofcourse Startapp is not accepted for family policy. So remove the Startapp ads and use Admob instead.
