title: Force Closed captions on smartphones
body: <p>I don't know if this kind of question can be answered here but here it goes.</p>
  
  <p>I have some videos uploaded on youtube with closed captions. I'm using the yt:cc=on tag to force captions to be displayed always wich is what I want with the exception that using an Iphone the captions are just not being displayed. </p>
  
  <p>Ipad works fine.</p>
  
  <p>I have been looking through the web and I can't find anything.</p>
  
  <p>Any help?</p>
  
  <p>Thx.</p>
