After reading lots of posts on the forum, it seems that lightbox videos are programmed to autoplay. However, my lightbox video (Vimeo) is only autoplaying on desktop. I know there have been some browser updates making autoplay tougher, but clicking a lightbox button to play a video seems like a sufficient interaction to merit playing a video without the user having to press the play button again.
I have checked all major browsers on desktop, and they all autoplay. I have also checked all major mobile browsers, and none of them autoplay. What am I missing here? Any help is appreciated.
