  <p>'An Error occurred delivering to the app store.'</p>
  
  <p>First I tried to release it directly from Xcode. Following the advice I found on here, I then tried it using Transporter. The same error occurred but I got an extended delivery log:</p>
  
  <blockquote>

  <p>Can someone help me fix this or point me in the right direction please, as I'm pretty lost with it.</p>
  
  <p>Many thanks</p>
