title: No advertisement is shown from Admob
body: <p>I had an Google Admob account which was banned by any reason (for 30 days, and I've no goddamn idea why) probably for "watching" the interstitial which I cannot avoid. </p>
  
  <p>I then had to create a new account on AdMob because I do not have the time to wait 30 days for this. </p>
  
  <p>I also have my iOS application linked to Firebase (On my old gmail account) which is linked to my banned AdMob account.</p>
  
  <p>I replaced my key in info.plist and googleService-info.plist
  I changed the app unit ID.</p>
  
  <pre><code>        interstitial = GADInterstitial(adUnitID: "ca-app-pub-MY-ID-is-here")
          let request = GADRequest()
  
          request.testDevices = [ kGADSimulatorID]
          interstitial.load(request)
          interstitial.delegate = self
  
  </code></pre>
  
  <pre><code>                                    if self.interstitial.isReady
                                      {
                                          self.interstitial.present(fromRootViewController: self)
                                      }
                                      else
                                      {
                                          print("Advertisement is not ready!")
  
                                          self.performSegue(withIdentifier: "History", sender: self)
                                      }
  </code></pre>
  
  <p>No ads is being displayed on the application, but why? Is it impossible to add advertisement to this right now? Even thought I changed my account?</p>
  
  <p>The new account is NOT linked to the Firebase, does that matter?</p>
  
  <p>I expect advertisement to show up but it doesnt.</p>
