Vimeo play on android devices

[ryan-ventralis]

I've come across a problem when using an android phone.
I've tried a few different devices such as the samsung galaxy s7 and s8.
the problem is whenever I click play on the video it pushes to the top of the screen, seems like it full screens the slit slider at the top.
I can't scroll or do anything but it seems the video is playing behind the slit slider because the music is playing.

really not sure what could be causing this.
