Cant watch youtube video full screen (mobile)

Design help General
1

I set it up so that when in mobile view I have a youtube video but watching it vertically isn’t optimal so I would like to watch it in full screen, but as I press that option the video continues to play but I’m shown my site instead.
I’m using Webflow free currently
