title: Youtube Iframe Embed won't autoplay on mobile
body: <p>I need to make a Youtube embed autoplay on a page. Usually setting autoplay=1 would work if it was paired with mute=1 in the query string params.</p>
  <p>This actually works fine on desktop, but it doesn't work on either Android or iPhone, no matter which browser.</p>
  <p>Did something change with the autoplay policies which would totally disable autoplay on mobile?</p>
