I'm having this problem too. Apparently, a lot of people are. I contacted the help center and got this reply: I'm sorry you're experiencing an issue with your PayPal account. There is an open ticket CSTS0031782 in regards to the system not allowing our customers to create invoices. Our back office team is working diligently to have this resolved as soon as feasible.
