title: Favicon in React will not Update
body: <p>I cannot update the favicon in react boilerplate. </p>
  
  <p>I replaced the file in images/app/favicon.ico with my own file, but I'm still seeing the old icon show up. </p>
  
  <p>I cleared my browser cache, ran <code>npm run build:clean</code>, and <code>npm run build</code>. </p>
  
  <p>Can't get my new favicon to render. Please advise how to update the favicon.</p>
