I setup my booking setting to accept all future bookings. My guests usually book my house 1 or 2 years in advance. But airbnb only allow 12 month snyc in their calendar. They don't sync the bookings to other website if they are 12 month futher out. or other website bookings cannot be synced with airbnb calendar if the bookings are more than 12 month out. I got several of double bookings because of this issue. when I called airbnb support, they blamed other website . I have no problems to sync to data with VRBO, booking.com, my own website.
airbnb does not want to take action to fix the problem. I don't know if you guys have problem with airbnb. I do have a serious problem with them.
airbnb does not even support deposit to book the house. my guests have to pay in full for their bookings even they booked 2 years in advance!!!
