Responsive issue regarding the Payment window.

[jivasingh]

The UI of the PayPal in the sandbox mode is not responsive on mobile, all the fields and text are having small fonts which are not handy to use. Please suggest a way so that I can make the changes and make it responsive.

Hello,

Your loading the checkout page which is designed for desktop usage, which is why the layout doesn't look right on a mobile device.

If you're integrating for mobile devices, use the checkout SDK instead for in-context mobile experience.
