I was having the same issue Peter, It seems to be working again now but I did lose a booking with a local businessman when he could not find the listing for his extended family to stay over Christmas. It was available, calendar was free for the entire month, Listing just not showing up regardless of the number of guests put in. I know this does not help, just said I would chime in and let you know you are not alone.
Thank you @Tom4999 for sharing your experience! Did you do anything at all to get it resolved?
@Peter4707 I see you have two listings, if you tell us which one you are having this issue with, perhaps other hosts will be able to help you investigate 🙂
