Google replied. Not sure why they replied regarding an outdated version (apk v1. Currently at apk v5) and not the most recent one, but here' what I got:
Status: App not available on Google Play
I’ve reviewed your appeal request and found that your app still violates Google Play Policy. I’ve included details below about the specific issue with your app and what you can do to get your app back on Google Play.
Step 1: Fix the policy violation with your app, SC Scramble (com.jsa.scscramble)
We have detected that your app (Apk version code: 1) includes non-certified ad SDKs and/or SDKs that are not approved for use in child-directed services. Any SDKs used in the app must be appropriate for use in child-directed services. Additionally, apps that solely target children must not contain any SDKs that are not approved for use in child-directed services, including ads SDKs. Apps in the Designed for Families program must only use ad SDKs that have certified their compliance with the Families Ads Program.
We have detected the use of Amazon SDK, which is not allowed in apps that are in the Families program. An ad SDK is not allowed if it has not self-certified its compliance with Play’s Families Ads Program (certified ad SDKs), or it is non-COPPA compliant per its own public documentation. Please note, the status of SDKs often changes and it is your responsibility to review documentation of all SDKs used in your app to ensure compliance with Families policies.
Please update your app to fix this issue.
