title: I can't autoplay vimeo video (mobile)
body: <p>I'm trying to <em>autoplay</em> a video included in a <code>iframe</code> on mobile devices.</p>
  <p>The app works well, but the user must click on the button inside the iFrame to play the video.</p>
  <p>I already tried to use the <code>&quot;autoplay=1&quot;</code> parameter in the <code>iframe</code> but it didn't work on mobile (on desktop well).</p>
  <p>Can you help me?</p>
