Yes, others got this (including me). It's related to an ongoing issue with some accounts being inadvertently converted to the new payment system... but your account likely just got the email, not the change. Check to make sure a regular traveler sees a booking button on your listing. If not, then contact CS in a hurry and let the mods here know your listing number to get the issue escalated to the team trying to get this fixed.
I'm going to direct you to the main discussion on this issue and lock this discussion so everything stays in one place.
