PayPal’s instuctions on cancelling subscriptions are wrong. I’d know, I spent the morning trying to figrure it out. As of the date this post was published, here’s how you actually do it:
Log into PayPal and click Summary.
Under Completed, click the transation for the recurring payment you want to cancel
Click “Manage XYZ payments”
Scroll to the bottom of the page and click “Cancel Subscription”
Rinse and repeat.
PayPal will then send you an email confirmation.
