Background video problems


I’m new to Webflow, and are running into some early problems.

Problem 1: I have added a background video, but is not playing on mobile, even though I have pasted a script which is supposedly working.

Problem 2: The video gets cropped on tablet view. It fills it’s box just fine on desktop, and mobile, but on tablet it’s suddenly zoomed in and it looks rubbish.

See screen recording of problem 1 and 2:
