title: Where is the certificate input when I edit configure of iOS notification on PushWoosh
body: <p>I remember that we have 3 fields when editing configure of iOS notification:</p>
  
  <ol>
  <li>Certificate</li>
  <li>p12 file</li>
  <li>password of p12 file</li>
  </ol>
  
  <p>But now I don't see "certificate" input. What happened?</p>
  
  <p>Is it OK without certificate file?</p>
