Paypal Place Holder Customization


sorry if the question sound silly, but I'm unable to find where I can customize the paypal place holder page, before the buyer is redirected to paypal portal to execute the payment.

A lot of customer see the blank page (and don't even notice the text) so they click back and recreate the order several times.

The text in the place holder page is really small, there's a way to customize it ?

I have attached a picture to show what I'm talking about

Thanks for the help.
