title: Updated Apple Developer Site Won't Allow Add Device to Ad Hoc Provisioning Profile April 2013
body: <h2>Edit April 9, 2013</h2>
  
  <p>Apple responded to my bug report on this matter and reported that "The problem has been fixed." I have confirmed that the problem is fixed. I can now add devices to older Ad Hoc provisioning profiles that were created before the website update.</p>
  
  <p><strong>The problem is now resolved.</strong></p>

  <p>As of this previous weekend April 6, 2013, it appears impossible to add devices to my existing Ad Hoc provisioning profiles on the Apple Developer <a href="https://developer.apple.com/account/ios/profile/profileList.action?type=production" rel="nofollow noreferrer">Certificates, Identifiers &amp; Profiles</a> page.</p>
  
  <p>There are many questions on StackOverflow describing how to add devices to iOS Ad Hoc profiles, and that was a fairly straightforward task up until this weekend.</p>
  
  <p>I am still able to edit the device list for my Development Profiles.</p>
  
  <p><strong>Can anyone tell me how to add devices to my Ad Hoc Provisioning Profile on the new Apple Developer website?</strong></p>
  
  <p><em>Notes:</em></p>
  
  <ul>
  <li>This is definitely an <em>Ad Hoc</em> profile, not a App Store
  <em>Distribution</em> profile.</li>
  <li>It is impossible to uncheck the radio button below: "iOS
  Distribution...".</li>
  </ul>
