title: PayPal IPN Sandbox - Changing the Notification URL will not update
body: <p>I had set a URL as my 'Notification URL' - <a href="https://example.com/ppl-name1.php" rel="nofollow noreferrer">https://example.com/ppl-name1.php</a> - in my PayPal sandbox account.
  It worked fine and testing went well.
  I decided to rename my 'Notification URL' to <a href="https://example.com/ppl-name2.php" rel="nofollow noreferrer">https://example.com/ppl-name2.php</a>.</p>
  
  <p>I updated the detail with the new URL here: <a href="https://www.sandbox.paypal.com/cgi-bin/customerprofileweb?cmd=_profile-ipn-notify" rel="nofollow noreferrer">https://www.sandbox.paypal.com/cgi-bin/customerprofileweb?cmd=_profile-ipn-notify</a></p>
  
  <p>It accepted and saved the new URL.</p>
  
  <p>But now paypal still sends the notifications to the old URL.
  No matter how many times I try - even deleting the saved URL setting and turning off notifications and turning them back on.</p>
  
  <p>It still will not send to the new URL.
  Yet it clearly shows the new URL as the saved value.</p>
  
  <p>I have verified the old URL is being called in the IPN History page.</p>
