I was able to solve it. It was the solution provided by guys from the engineering:
In the Billing page, enter the credit card information
Before clicking Save, open the browser Dev Tools:
Safari & Chrome: command-option-I, or,
Right click, Inspect Element
Click the Save button
Click the Continue button when the ‘Card Authentication’ pop-up displays
Click the Continue button at the bottom of your bank's detail page
If a blank page appears, please:
a) Right Click on the blank pop-up -> Inspect Element
b) Within the iframe element, open the html element, then open the body element.
c) Expand the script element, highlight the code, right-click and Copy as Text
d) Within the Dev Tools Console, paste the copied text at the console prompt
e) Within the pasted code, find PaRes: and change the single quotes at the start and end of the code to back tick (`). Be sure to only change these two single quotes.
f) Press enter
g) A response from your bank should be shown in the pop-up.
