Hi Alex,
Thank you for contacting the Mobile Ads SDK Support team.
Please note that the test ID: ca-app-pub-3940256099942544/3986624511 exclusively returns test Ads. The Demo ad units are not associated with your AdMob account. Make sure you replace these IDs with your own ad unit ID before publishing your app.
For Native Advanced Ads, the "Test Ad" label is not an overlay. The string "Test mode" is prepended to the ad's headline. If the ad is from a third-party network, it will never show the AdMob "Test Ad" label.
Could you confirm whether you have followed all the steps mentioned in the Enable test devices document to add your device as a test device.
Kindly check whether the mentioned issue is reproducible in our sample project? If the issue still persists, Kindly provide the below information via reply to author option for further investigation:
