How do i show I accept credit cards?

There is no longer a place to tick which credit cards you accept. The checklist that used to sit on Edit Listing > Settings > Payment & Policies has been removed, and that page now holds only your Payment Policy, your Cancellation Policy and your Notes.

Which cards a guest can use is decided by the payment processor you connect at Settings > Connected payments (houfy.com/settings/payment-settings) - Stripe, Square or PayPal. The guest sees the brands that processor accepts on the card form at checkout. There is nothing for you to switch on.

If you run a classic Houfy host website and its Cards accepted block shows brands you no longer take, contact support: that block still displays a setting saved before the checklist was removed, and there is no screen left to change it.
