title: Angular universal Server Side Rendering, Meta tags
body: <p>I moved my site to Angular universal SSR,
  during my move I encountered some problems that I thought ng-universal would fix.</p>
  
  <p>I want to add meta tags such as description, keywords etc (different for each page).</p>
  
  <p>Using the <code>titleService</code> as angular suggests works just fine, it changed the title of the pages. However if I land on homepage and then navigate from there to other pages, the title is not changing, but when I look on source I see the change in the source but no on the tab of VIEW. If I land on the page (or hit refresh) the page is updated with the correct title.</p>
  
  <p>I tried  to add in additional to the title meta tags, but nothing works:</p>
  
  <pre><code>this.meta.updateTag( {name: "description", content: 'test1234});
  
  this.meta.addTag({name: 'description', content: 'Content description' });
  </code></pre>
  
  <p>OR</p>
  
  <pre><code>using vanilaJS
   var doc = (&lt;HTMLMetaElement&gt;document.getElementById('description'));
  doc.content = "test1234";
  </code></pre>
  
  <p>the meta is not changing in the header section.
  I have no idea why.
  any help can assist..
  thanks</p>
