PayPal provides two different checkout layouts. I would use the oldest layout (so not the enhanced). How can I set this preference? Is there some special variable to do that? Or I should do that from profile settings page?
Thanks
By adding force_sa=true
in your calling Url, you can still use the old layout
Check that Paypal express "order summary" page
You cannot. The new (enhanced) layout is gradually being rolled out. The old one will disappear over time.
