I had to contact AirBNB about the same thing last week. I created a listing to host back in July, but I got a private short term tenant for four months, so I hid the listing. When my private tenant gave 30 notice to vacate I opened up the listing again. I got nothing. No views, no inquiries...NOTHING. I finally contacted AirBNB and the CSR rep said my listing was not even coming up in a search perameter specific to my rates, area and amenities. That was quite upsetting! My issue was referred to their IT Dept, but I wasn't expecting much because it's the holiday season.
I did start seeing views within a few hours and my first guest arrived last night. I don't yet know if they actually fixed the issue or if the booking was a fluke. We shall see.
