title: Rewarded video from AdMob in Unity - loading so slow
body: <p>Previously I used Unity Ads to display interstitial and rewarded ads in my game made with unity but now I'm switching to Google Ads (AdMob).</p>
  
  <p>I read documentation from <a href="https://developers.google.com/admob/unity/start" rel="nofollow noreferrer">here</a> and next from <a href="https://developers.google.com/admob/unity/rewarded-video" rel="nofollow noreferrer">here</a> and everything seems like it's working, but kinda slow.</p>
  
  <p>I have 3 scenes:</p>
  
  <ul>
  <li>Main Menu</li>
  <li>Game</li>
  <li>Shop</li>
  </ul>
  
  <p>I need to display rewarded ads in Game and Shop scenes. In the Game scene, the user has the ability to watch an ad to continue where he dies. He have <strong>only 5 sec</strong> to do that. If he doesn't watch an ad, then he has the ability to watch another ad for +25 coins, to restart the game or to go to the main menu. From the Main Menu scene, the user has the ability to go to the store to buy some more characters and here he also has a button for +25 coins if he watches rewarded ad. So, there are 3 places for the rewarded ad.</p>
  
  <p>In the Main Menu script, in the <code>Start()</code> method there is:</p>
  
  <pre><code>MobileAds.Initialize(appId);
  </code></pre>
  
  <p>The problem is, when the user clicks on the "Store" button in the Main Menu scene, in the <code>Start()</code> method I'm calling</p>
  
  <pre><code>// Create an empty ad request.
  AdRequest request = new AdRequest.Builder().Build();
  // Load the rewarded video ad with the request.
  rewardBasedVideo.LoadAd(request, adUnitId);
  </code></pre>
  
  <p>and the user has the ability to immediately click on "View ad" button which does this:</p>
  
  <pre><code>if (rewardBasedVideo.IsLoaded()) {
    rewardBasedVideo.Show();
  }
  </code></pre>
  
  <p>and there is a problem... Rewarded ad is still not loaded, it will be loaded after 1.5s - 2 s from calling <code>rewardBasedVideo.LoadAd(request, adUnitId);</code> So, the user must click it multiple times until ad appears.</p>
  
  <p>I checked a lot of other games which uses AdMob and every game immediately show ads. How? Is there a way to preload rewarded ad?</p>
  
  <p>It's also a bad UX when die modal appears and user have 5s to watch rewarded ad until he is "fully dead" but the ad is available after ~3s.</p>
  
  <p>Also in the store, after watching the ad, user has ability to watch it again, so in <code>OnAdClosed</code> I putted the same logic for loading new ad but it's also slow and after few seconds the ad is actually loaded and I tested other games - they don't have that problem.</p>
  
  <p>Do You have any advice?</p>
