Why Isn't PayPal Checkout Finishing for My Customers?

If your customers are attempting to check out using PayPal and report that the process never seems to complete, this issue is most likely related to the popup function that PayPal utilizes within its checkout flow.

To resolve this, the customer must enable pop-ups in their web browser's configuration settings. Once pop-ups are allowed for your site or for PayPal, the checkout process should be able to finish successfully.
