title: Native app install banner not working
body: <p>I cant get a native app install banner to display on android. I've added the following <code>masifest.json</code>:</p>
  
  <pre><code>{
      "name": "My native app",
      "description": "balh blah blah",
      "short_name": "myapp",
      "icons": [
          {
              "src:": "/Assets/app-install-banner-logo.png",
              "type:": "image/png",
              "sizes:": "144x144"
          }
      ],
      "prefer_related_applications": true,
      "related_applications": [
          {
              "platform": "play",
              "id": "com.my.app"
          }
      ]
  }
  </code></pre>
  
  <p>When I look at the application tab in chrome dev tools is see: </p>
  
  <p><a href="https://i.stack.imgur.com/k5LX4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/k5LX4.png" alt="enter image description here"></a></p>
  
  <p>Why isn't are the fields begin populated? The json is valid, I can click on the <code>/Assets/manifest.json</code> link and see the contents. What am I missing here?</p>
