Using Paypal WPS, when someone cancels reoccurring payment on a monthly subscription, it wipes all roles immediately

Hello

I did my due diligence and search for an outstanding issue on this one but if it is a duplicate, I apologize.

We currently have a subscription based site with a variety of products. Some are full term payment subscriptions and some are reoccurring. For our reoccurring, we set it up to be monthly. We are finding that when someone cancels their reoccurring payment in paypal, it makes contact with our site which then immediately removes all their roles assigned at purchase instead of waiting until the end of the month to drop their subscription.

Not sure if anyone else has experienced this or found a way to mitigate it.
