title: AdMob Legacy Publisher ID not showing ads
body: <p>My iOS "AdMob Legacy Publisher ID" not showing ads, started yesterday and not getting any ads today.  I tried using the new "Ad unit ID" and it works.</p>
  
  <p>This sucks because now all my apps in the app store are not showing ads.</p>
  
  <p>Error Domain=com.google.ads Code=1 "Request Error: No ad to show." UserInfo=0xa28ff90 {NSLocalizedDescription=Request Error: No ad to show., NSLocalizedFailureReason=Request Error: No ad to show.}</p>
  
  <p>Anyone else having this issue?</p>
