@WoozleB,
You can update your Facebook Messenger notification preference in your PayPal account's Settings. If you're still seeing this issue on your end after completing the steps, I recommend contacting our customer service teams for further assistance. You can click 'Contact Us' at the bottom of any of our pages to get a phone number to reach us at, or you can contact us on Twitter (https://twitter.com/askpaypal) or Facebook (https://www.facebook.com/PayPal). We would be happy to take a look at what options might be available to you.
