title: Visiting my custom Facebook tab app doesnt work on mobile?
body: <p>I've currently setup a custom tab app on my fanpage - visiting this is working perfectly fine from my browser.</p>
  
  <p>However when visiting the same url from my mobile, I just get some red text on Facebook saying "The page was not found".</p>
  
  <p>I've defined the following (noteworthy) settings for the app:</p>
  
  <ul>
  <li>Namespace (which gives me a canvas page)</li>
  <li>Canvas url</li>
  <li>Secure canvas url</li>
  <li>Page tab url</li>
  <li>Secure page tab url</li>
  </ul>
  
  <p>I then also tried to fill out the "Mobile site url" with the same url as the canvas url - thinking this was the missing brick? But atleast not difference.</p>
  
  <p>Any ideas?</p>
