Hey SlickMick, thanks for picking up these issues - we're working on it.
You may have ad blocking software in Chrome which is stopping the Shake It button from progressing. Try disabling the software temporarily so you can allow access.
Until we get to the bottom of the Firefox for desktop issue, I recommend trying on your mobile device. Should have this sorted soon.
Can't get page to work in Chrome (Shake It button locks up) or Firefox (no button)!!??
