title: iOS In-App Purchase Auto renewable subscriptions disabled by user
body: <p>I've been searching for this answer for quite a while, but it seems confused while I got different answers which is not yet solving my question. However, I couldn't test this situation through sandbox environment too... </p>
  
  <p>The question is simple:
   While user disables the <strong>auto-renewable</strong> subscription, what is the result returns when validating receipt through <a href="https://buy.itunes.apple.com/verifyReceipt" rel="nofollow noreferrer">https://buy.itunes.apple.com/verifyReceipt</a> ?</p>
  
  <p>(a) return status = 0, receipt is valid. You couldn't check whether user has disabled the auto subscription. </p>
  
  <p>(b) return status = 21006, receipt is valid. This happen while the subscription reached expiration date? (I have no idea how this happen since I couldn't test this out)</p>
  
  <p>(c) you'll have <code>latest_expired_receipt_info</code> if user disables the receipt. (This is what I found from here <a href="https://stackoverflow.com/a/18161118/3871220">https://stackoverflow.com/a/18161118/3871220</a>, but honestly, I can't have this field after my test account has reached limit(6 auto-renew purchases).</p>
  
  <p>Therefore, I really need someone who has experience with this, gives me a clue and I would be appreciate that very much!</p>
