  • This will not display PDAPPS environments. Any publicly accessible URL and DataCenter URL's should work fine.
  • Entry of the URL needs to follow the form of the input placeholder, ie http:// or https:// is required in order to get the URL to populate.
  • If the view looks a bit off when switching from viewport to viewport, right click on the middle of the page and choose "Reload frame" from the contextual menu. This will refresh only the iframe that's holding the URL you're looking at.
