@Sharon688 You said they were "Requests to Book". If you just messaged back this information, without Accepting or Declining, and they didn't book, there would not have been any cancellations involved. Did you Accept and then they cancelled? Did you get a messsage asking you to accept the guest's cancellation? If so, never accept it if you get that message- it's a really sneaky thing Airbnb does and goes down as a host cancellation. If a guest wants to cancel, they can do it all by themselves, without your approval.
