i received this message from google developer console :
all my apps
have been removed from Google Play. These apps won’t be available to users until you submit a compliant update.
Policy issue: Your app violates the Android Advertising ID policy. All updates and new apps uploaded to the Play Store must use the advertising ID (when available on a device) in lieu of any other device identifiers for any advertising purposes.
Here’s how you can submit your app for another review:
Sign in to your Play Console and note the libraries or SDKs listed in the ‘Policy Violation’ alert on your app’s dashboard.
Remove any non-compliant library or SDK from your app. You may need to contact your app SDK provider for an updated, policy compliant version.
Read through the Android Advertising ID article for more details and examples.
Remember that your app must comply with all other policies listed in the Developer Program Policies and additional enforcement could occur if there are further policy issues with your apps.
Submit your app again.
If approved, your app will again be available with all installs, ratings, and reviews intact.
Thanks for your assistance and continued support of Google Play.
