title: Flutter: Admob Ios Rewarded Video with real AdUnitId doesnt work, but works with testid
body: <p>So I'm trying to add admob's Rewarded Videos to my Flutter Project. </p>
  
  <p>1) specifying targetingInfo</p>
  
  <pre><code>  static final MobileAdTargetingInfo targetingInfo = new MobileAdTargetingInfo(
    testDevices: &lt;String&gt;[],
    keywords: &lt;String&gt;["many", "keywords"],
    childDirected: true,
    gender: MobileAdGender.unknown,);
  </code></pre>
  
  <p>2) Differentiate Ios and Android</p>
  
  <pre><code>if(isIos)FirebaseAdMob.instance.initialize(appId: "ca-app-pub-xxxxxxxxxx~xxxxxxxxx");
  else FirebaseAdMob.instance.initialize(appId: "ca-app-pub-yyyyyyyyyyyy~yyyyyyyyyy");
  </code></pre>
  
  <p>3) load ad method</p>
  
  <pre><code>loadNextAd() {
  print("loading started");
  if(isIos) RewardedVideoAd.instance.load(adUnitId: "ca-app-pub-xxxxxxxxxx/xxxxxxxx", targetingInfo: targetingInfo);
  else RewardedVideoAd.instance.load(adUnitId: "ca-app-pub-yyyyyyyyyy/yyyyyyyy", targetingInfo: targetingInfo);
  </code></pre>
  
  <p>}</p>
  
  <p>Everything works fine with the Android implementation, and Ios works with the RewardedVideoAd.testAdUnitId, but as soon as i use the real one it fails to load. I also read that that, if you are able to show a testad, your implementation is alright.</p>
  
  <p>I researched quite a bit and found Googles testproject to try out adunits (<a href="https://github.com/googleads/googleads-mobile-ios-examples/tree/master/Swift/admob/RewardedVideoExample" rel="nofollow noreferrer">link</a>). It worked there and showed me my ad, but it just wont load in my project. All i get is a <strong><em>"Request Error: No ad to show"</em></strong>.</p>
  
  <p>I also read that it could take some time until the adunit is active but i created it 3 days ago so it cant be that, can it? 
  Any help would be really appreciated, kinda desperate right now.</p>
