So when I follow the tutorial, adding the code as described, it breaks functionality in my app. The primary and repeatable issue is that as soon as I add trackPage('about'); to the page, the footer navigate page buttons no longer work in the web preview or native app install. I delete this code and all is normal. Now, the workaround appears to be that a full page refresh be enabled for the navigate to page. That is NOT a viable solution. Debug is not showing an error. The button simply does not fire, the listening handler seems 'off'. ??
