Welcome! Your listing goes live 24 hours after you hit the button to make it go live.
During that time however please go back to your listing and fill out the arrival guide and some other things that are not available until you hit the post button to make it go live. I was surprised when I signed up I couldn’t do this all before making the listing go live.
Do check your listing as a guest (not logged in) to make sure the formatting, picture presentation, house manual, guidebook and everything is set up to your liking.
