If a customer uses the PayPal Smart Button Payment method at checkout. Since there is only one payment method setup, it skips down to 'Payment Information' where the PayPal Smart Buttons should be. These buttons are missing on iPhone displays. It shows on the computer or on Android devices that I've tested. I'm using the latest plugin version 1.06 on Nop 4.20
