Pay once at Netflix as a member of a 4x account?

Hello dear Gutefrage community,

I'm a member of a 4x User Netflix account, but I'm not the owner of this account (it's a friend). I'd like to take over the upcoming payment for this month, but don't want my PayPal to "log in" for the next billing.

Because when I go to 'Add payment method,' it says "Your new payment method will be used starting with the next billing period." Which isn't what I want. I only want to pay this one upcoming bill. Is that okay?

Have a nice evening! 🙂
