Android support?

I've tested in modern browsers on desktop and iOS, but when testing on Android devices the animation doesn't seem to trigger, however it displays in the end state which makes me think it fires on page load instead before scrolling.

I've just tested it on an android phone on firefox and chrome and it works on my end.
