I am also looking for a way to autoplay a Canvas Studio video. The HTML is in a format that doesn't seem to allow the "autoplay" code. I do see autoplay in the HTML, but there is no option in video to make it autoplay. The video i am lookin to replay is a Canva project i converted to a Studio video. It will play when i click "play", but I want it to autoplay when the page loads. This really is a question for any Canvas Studio video. Here is the code below for reference:
