Video Header questions

Hi All! I haven’t been able to get my video header to play on mobile phones. It will play on desktop computers and on some tablets. Is there a way to have it play also on mobile phones and tablets?

2. Everything I’ve come across indicates that I can’t have my video header play on everypage of my website that a visitor clicks on: it only plays on the main landing page. Is there a way to make it play on each page a visitor clicks on? Thank you in advance for your help.
