Paypal Pro: looking for the option to restrict or uncheck types of card

In JotForm v3, it was possible to modify the options in the PayPal Pro module to only accept payment from specific credit cards.  I can't seem to find a similar option in v4.

As far as I know, there was no option to restrict specific credit cards with the payment integration. Could you provide us with more information with the option that you are looking for?

We will wait for your response. Thank you! 

In v3 of JotForms, there was an option for the PayPal Pro module to deselect certain credit cards (e.g Discover, Amex, etc) if you didn't want to accept them.

Sorry but I too don't remember any option to specifically allow/disallow certain types of credit cards in Paypal, Paypal Express or Paypal Pro in our previous Form Builder. Is there any resource you can point us to (e.g. a screenshot, a thread, etc.) that will help us better understand what you're referring at?

I'd definitely be curious to know as well if there's an option to do that. What I do know is that PayPal Pro allows you an option to choose the Default Payment Method (whether it's through PayPal or Credit Card):

Here is a screenshot from the v3 editor:

As you can see, there is an option for "Selected Cards" and you can use the checkboxes to allow or disallow certain credit cards from being processed in the PayPal Pro module.  Where would I find a similar option in the v4 editor?

As far as I know, that option is not connected with Paypal. That is just to hide the other card icons or show it, but still, Paypal accepts it for payments. But let me forward this thread to our developers to confirm. If there are updates, you should know it through this thread.
