Braintree payment method Laravel

I have fully operational payment with laravel cashier, but something I don't understand. When I pay first time with PayPal, payment is successful, when I pay again, using tge default Braintree form (drop-in), but this time with VISA, my payment again goes to PayPal. How can I change payment method? What is the best practice? Can it be done automatically, if I pay VISA to change to VISA? Also, I will be thankful someone clear me process of updating card? Thank you.
