It is still very frustrating. There have been some "improvements?" though...depending on what date a guest tries to book. In some cases the only checkout date allowed is the next day, in other cases it is a 4 day window, some it is a 3 week window.
I had another chat with CS who again stated it is a known glitch and I am on the list. She also said it could take a week or two to resolve and I should call back after a couple of weeks if it is still a problem. At least the CS agent took the time to review all of my settings with me, go to an incognito window and see the issue first hand, and express what sounded like genuine regret this is happening and an understanding of the impact on my business. She acknowledged it was on their end and not something I had done wrong. The first two CS reps sounded like they were reading from a phony script - overly solicitous with platitudes and a "just don't worry" spiel.
I have had one booking for March. March is traditionally one of our busiest months.
I have been an advocate for Airbnb in my community, have informally mentored new hosts (one only a block from me), and have always been enthusiastic about my role as a host. It is hard to maintain a positive attitude when feeling like I am not getting support as a host and my business is nonexistent. Fortunately, this is not my main income stream, however, that does not make it less frustrating.
