I'm trying this plugin as well as I have a lot of return customers on my site... I've installed the plugin and it seems to work from what I can see.
My question is - is there not a way we can choose the content that's shown on the Paypal Checkout button? The reason I ask is because currently, the button just says "Paypal Checkout". The word "Express" is not displayed on there so I think people may think that it's the same as the standard Paypal checkout.
