you are using PayPal for your eStore, we have added a feature to auto-redirect to PayPal once the customer's order
has been completed. Before the change, the customer would have to click on the
PayPal button on the summary page to log into their PayPal account to pay for
their order. Customers who had pop-up blockers installed would sometimes
have problems getting to this page. Now with the auto-redirect
enabled, it will automatically take the customer to PayPal login page.
feature is not enabled by default. You can enable it by going to Settings
> Payments > Auto Redirect to PayPal Site.
