title: Removal of in-app purchase product in itunes connect
body: <p>I want to change the type of in-app purchase from auto-renewable to non-consumable one.<br>
  So I remove the in-app purchase product in itunes connect and create a new one.<br>
  The problem is when restoring, does old users who had ever purchased the auto-renewable receive the old transactions back?<br>
  <br>
  I have another problem now. >_&lt;<br>
  1. I remove the old auto-renewable product.<br>
  2. Add a new non-consumable product.<br>
  3. Add a update version of my app.(ex. 1.3.0)<br>
  When I try to test in-app purchase with new product in sandbox, I receive 21004 when I verify the receipt with app-store. I cannot find any definition of error 21004 on non-consumable product.<br>
  Only auto-renewable product defines it. It means shared-key not match.<br>
  But receipt verification of non-consumable product didn't need shared-key.<br>
  <br>
  Does someone teach me what happen?<br>
  Thanks.</p>
