I don’t think so. I have the circle card but it gave me the option to change to a different card. Just checked and I can input any form of payment. Just clarifying you’re not paying for the service it’s free, the payment is for purchases you make.
Me and another fellow team member signed up today and it was free. We have a red card so I don’t know if that makes a difference. The free offer didn’t show up in the app until today.
