I'm using Magento 22.214.171.124 with latest updates installed and a custom Theme that I paid for. If a customer checks out and gets to the payment section, he/she enters credit card information and will be able to see everything on the screen EXCEPT the CVV. If you try to add anything in that box, nothing shows up and it seems like that field is not allowing numbers to show up.
I've tested an actual transaction on (Live) and I was able to complete the transaction. The issue is if you don't click and add any numbers in the CVV, you will get the error message that you're missing the CVV. but you can click on it and type the "invisible numbers" and it will complete the transaction.
How can this be fixed? I would like to allow numbers to show for the customer or remove the CVV completely.
PS: I'm using Paypal pro
Can you inspect your code to see if the CVV text is not being hidden? Sounds like someone updated that box to be white on white resulting in "invisible numbers".
