Kids app rejected by Play Store due to AppMetrica transmitting Advertising Id

We have added the AppMetrica Plugin for Unity to our kids app. The app targets age 5 and under so it must comply with the Google Play Designed for Families policy. The policy states in Section 5. Data Practices:

“You must not transmit Android advertising identifier (AAID), SIM Serial, Build Serial, BSSID, MAC, SSID, IMEI and/or IMSI from children or users of unknown age.”

When we run the app we can see the Advertising Id (oaid and adv_id) being transmitted in a request to an appmetrica endpoint (see screenshot attached).

Is there a configuration option I’m missing that prevents the Advertising Id from being transmitted? We have enabled the AppForKids flag in the configuration but this seems to be for iOS only. We have also followed the instructions in Step 3 of the AppMetrica Android Installation and initialization section to remove the AD_ID permission from the application manifest but nothing changed.

If we submit the same app with AppMetrica disabled it passes and we can publish.

Any ideas on how we can fix this would be much appreciated.
