Hi,
I have built a new store in Dawn theme and used code from a youtuber to create a hero banner video that includes text and buttons.
The challenge is I cannot get the video to play on iOS. It works perfectly on desktop and Android. I’ve tried several ‘fixes’ from different youtubers but nothing works 
The code I am using is below.
All help very gratefully received! I am not a coding person so please keep it in simplistic terms and state the obvious (because it won’t be obvious to me!!).
Thank you
