I also have the same problem like yours. I have listed my property for more than 2 years and my business went very well in the first 2 years.
Recently, I received less bookings and I try to search for my property to see is there any thing wrong and I cannot my own property however i could see my neighbors' properties.
Some of your guests who wanted to extend their stay with us also could not find us on airbnb. They thought my property was full therefore they had to book another place while my room was empty on these days.
Our other guests who made a booking via tripadvisor also said that they could not find us through airbnb therefore they have to make a reservation via TA.

It would be great if you all can help me with this or do you have the contact detail of airbnb support team. Thanks
