We have been using this feature for a number of years now.  When sending an invoice with the 'review and pay' link, it used to take you to a page where you could either pay by debit card, pay by credit card or login to Paypal.  It now seems that the only option is to login to Paypal.  We have customers with company cards or who do not have Paypal accounts who can no longer use this feature.

The app is still advertised as customers not requiring a Paypal account to pay, but this isn't the case.
