title: metadata with deep-links to open my app on android and ios doesn't work
body: <p>I tried to open app store on mobile when user doesn't has this application and to open application when user has application.</p>
  
  <p>I added meta tags in header of new page open_chat.html:</p>
  
  <pre><code> &lt;meta property = 'al:ios:url'  content = "realagent://chats"/&gt;
    &lt;meta property = 'al:ios:app_store_id' content = "11111111"/&gt; 
    &lt;meta property = 'al:android:url'  content = "realagent://chats"/&gt;
    &lt;meta property = 'al:android:package' content = "com.application"/&gt;
  </code></pre>
  
  <p>After, I do to this page open_chat on mobile and its not redirect me to the app store.</p>
  
  <p>What I doing wrong?</p>
