title: Unable to update to Xcode 8.3
body: <p>When I tried to update to Xcode 8.3, the following happened in App Store (it has been like this for over an hour):</p>
  
  <p><a href="https://i.stack.imgur.com/tnIFd.png" rel="noreferrer"><img src="https://i.stack.imgur.com/tnIFd.png" alt="enter image description here"></a></p>
  
  <p>So it just says "loading" and nothing happens.</p>
  
  <p>What I already tried:</p>
  
  <ul>
  <li>Mac restart</li>
  <li>Logoff and Login to the App Store</li>
  </ul>
  
  <p>Any ideas?</p>
  
  <p>btw: My Apple membership expires in 5 days - could this be a problem? </p>
