Application. Received Google message received: Violation of Usage of Android Advertising [duplicate]

Question

I've just received this message from Google Play but I'm not collecting the Advertising ID.

Reason for warning: Violation of Usage of Android Advertising ID policy and section 4.8 of the Developer Distribution Agreement

Google Play requires developers to provide a valid privacy policy when the app requests or handles sensitive user or device information. We’ve identified that your app collects and transmits the Android advertising ID, which is subject to a privacy policy requirement.

Is it possible any of my dependencies uses it? Here's the list of dependencies:

implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation "org.jetbrains.anko:anko-common:$anko_version"

implementation ("com.android.support:appcompat-v7:$android_support_version") {

Disable advertising id collection

According to the Firebase docs you can disable advertising id collection by setting:

<meta-data android:name="google_analytics_adid_collection_enabled" android:value="false" />

in your AndroidManifest.xml under the <Application> tag.

EDIT: It seems like people are having mixed success with this approach. Try adding configurations { all*.exclude group: 'com.google.firebase', module: 'firebase-core' all*.exclude group: 'com.google.firebase', module: 'firebase-iid' } to the Gradle app dependencies area as per comment below.
