I've got a listing with smart pricing on and I have set a minimum and maximum price.
Today I got a booking for less than 1/3 of the minimum per night.
In calendar view I see my Min price up top and I see my maximum price on the days either side but it's showing the new price as the reservation price and I don't know how it's got the price.
Did this issue get resolved for you? I've had the same problem now, where a booking was made for less than my baseline price on Smart Pricing. I have tried contacting Airbnb support but so far I am getting nowhere with them. I don't want to cancel the people who have booked, but they managed to get a booking at peak season for my ski condo for a fraction of the going rate. I'm really upset with the Airbnb platform right now.
