title: Not able to see any Yield Groups or Binding partner in AdManager's Mediation Test Suite
body: <p>I'm trying to add Meta as mediation partner in GAM and followed this <a href="https://developers.google.com/ad-manager/mobile-ads-sdk/android/mediation/meta" rel="nofollow noreferrer">doc</a> for that.
  After that when I try to test this implementation using <a href="https://developers.google.com/ad-manager/mobile-ads-sdk/android/mediation-test-suite" rel="nofollow noreferrer">test suite</a>, I'm not getting any Yield group or any binding partners.</p>

  <p>Ads were integrated in application a year ago using GAM and Admob and it's working fine, now we just wanted to add Meta as Mediation partner.</p>
  <p>Can someone please help me to investigate the problem here?</p>
