Mp4 video inside element grid does not play

[umfundisi]

I've put a Mp4 video inside an element grid and it will not play on click - could you please help me with this?
Tried: Chrome, Firefox, Safari

With Autoplay it works - but without it does not - already tried to mute and activated all different combinations of the options available but nothing helped so far.

Dear @umfundisi
I think I replied in another thread. The videos work here.

Best!
