Videos not autoplaying in tabs (HTTP 206 Partial content)

I have 6 tabbed sections, all with autoplaying videos, and for some reason when logged out I am not seeing the videos play. In dev tools I get the warning (HTTP 206 partial content loaded) for the videos.

I’ve tried deactiving all experimental options, and even referenced this blog: https://developers.elementor.com/how-elementor-improved-asset-loading-and-made-your-website-run-faster/

But I cannot get these videos to fully load on page load, and autoplay.
