title: Feature Policy Safari - Iframes - Youtube - ReactJS
body: <p>I am working on my website and noticed an error that I cant figure out that deals with Feature Policy. </p>
  
  <p>In Google Chrome, I do not receive the error but in Safari I do. 
  "Feature policy 'Fullscreen' check failed for iframe with origin '<a href="https://www.youtube.com" rel="nofollow noreferrer">https://www.youtube.com</a>' and allow attribute ''."</p>
  
  <p>I went and added "allow="autoplay; fullscreen"" to all of my youtube iframes but this has not solved the issue. Can anyone point me in the right direction?</p>
  
  <p>I have also used allowFullScreen and allowFullScreen='allowFullScreen'</p>
