google play says my app has ads...but it doesn't (does it?)

Please provide the following:

  1. SDK Version: 40
  2. Platforms(Android/iOS/web/all): Android

Having same issue as seen here: App flagged as "containing ads" on Google Play, though we don't have any

Google play has this warning under Policy Ad Content

We found ad SDKs in your app
Version: 6, SDK: AdMob
Version: 6, SDK: Facebook
If your app serves ads, you must answer 'Yes' to the question below. If you use ad SDKs but your app doesn't serve ads, you can leave your answer as 'No'.

I am not using Ads. Is expo injecting this code into my app? How do I resolve this?

Thank you,
