Hi, I'm trying to list a website for sale on the Marketplace. The add page says "First you need to link your PayPal account (so that you can receive payments)", but when I try to link PayPal at /account/third-party-accounts-link?service=paypal it says "You do not have permission to view this page or perform this action." Could someone tell me what's needed to link PayPal, or enable it for my account? Thanks!
