Your app is not compliant with Google Play Policies
I created an app an educational app that targets children. The app uses Admob to serve Ads. It has been published on the Google play store for few months.
Recently I received a mail form Google saying that :
"Action Required: Your app is not compliant with Google Play Policies"
Action required: Submit an updated app within 30 days.
Make appropriate changes to your app, and be sure to remove any non-certified ad SDKs or SDKs that are not approved for use in child-directed services. Remember, apps in the Designed for Families program that use ad SDKs for serving ads must only use ad SDKs that have certified their compliance with the Families Ads Program. Additionally, all other SDKs used in your app must be appropriate to be used in child-directed services.
How do I update or remove non-certified ad SDKs or SDKs that are not approved for use in child-directed services. Not sure where to start.
