What did Airbnb say when you asked them @Tanya778 . Have you had a recent guest safety issues ? Have they recently asked you to verify your ID sorry it's difficult to guess at what might be the issue based on the information you've provided .
it's always a risky approach to just rely on a single marketing channel such as Airbnb for such a volatile business as short term rentals . Do advertise on relevant listings channels and set yourself up to take direct bookings .
