ok, done.
So the screen height is reduced on mobile/tablet so you can hit the play button on the mobile.
But it still has a playing issue :
Tablet : Vimeo player starts on pause but then plays when you touch pause button, so thats a bit double dutch…
Mobile : Even though you can see the button now it refuses to play when you touch the play button.
I bought this theme for the fullscreen dropdown player because its different, you might consider a android or ios upgrade rather than the vimeo player?
