Lightbox vimeo not autoplaying on mobile

Webflow will not autoplay videos form a lightbox on mobile using Vimeo? You have to manually click play on the pop-up.

It works on desktop just fine. I have a Wordpress lightbox site that plays on mobile just fine.

Any ideas? I’m using all the link settings - muted=1&autoplay=1

Is your iPhone on low battery mode? Because background videos don’t play when that’s turned on.
