We have recently contacted PayPal support about why a certain subscription which failed to renew due to a problem in the funding source did not cause PayPal to send us a cancel IPN. Tech support said the reason was that we did not have a maximum limit on retry attempts. However we have set the "Reattempt on Failure" to 3,6,8 (I don't see this information anywhere on the user payment log). They(PayPal support) also made the following note: " The MAXFAILEDPAYMENTS field in the Profile Subscription ID XXXXX is set to indefinite and this is the number of failed payments allowed before the profile is automatically suspended. In the future please set the "Failed payments allowed" to the desired value. " Could you please comment/clarify this issue? Thank you.
