It looks like there is something preventing it from fully loading the page for you.  You can see that little bit of html script where the “play” button would be in the orange box.  I tested on my account and everything seems to be working.  I even toggled the flyby feature off and then back on to test the performance and it worked properly.  Might be something with your account or possibly the internet connection?  Have you tried from a mobile web browser using a cell service or from a device from a different location?  

Solved: It was the VPN. Although previously I had tried pausing it, I had to shut it off completely. Mystery over.
