App is rejected by Android for non-compliant Ad SDK, but not using ADs

Currently have an Android App built on Unity 2022.3.32 that has absolutely no Ads, though i am using In-App Purchasing. When i submit the updated app, it is being rejected for the following reasons. I am a bit lost in that i don’t have any Ads modules from either Unity or a 3rd Party, yet it is being rejected.

If anyone has insights to what I am doing wrong and how i can get this resolved, it would be very much appreciated. If i don’t get this update in soon, they will take the app down.

" our app includes noncompliant version of Unity SDK which collects persistent device identifiers and you may consider upgrading the SDK version used in your app to **4.0.1"

Thanks very much for the suggestions. I have double checked that the Ads Services is not enabled, which it isn’t. But in reviewing the AndroidManifest.xml files, to be honest, i don’t see anything explicitly Ads related, but I may be less than fully knowledgeable on what i am looking for.
