  <p>Tested with a virtual device in Android Studio. The ad is not displayed.</p>
  
  <p>And just to emphasize on this: The IDs shown are the sample IDs from <a href="https://developers.google.com/admob/android/quick-start" rel="nofollow noreferrer">https://developers.google.com/admob/android/quick-start</a>. The waiting period for newly created AD IDs does not apply here, as all answers I have found for the problem so far suggested.</p>
