I'm having the same issue....the listing automatically chooses the lowest price you have instead of your base price. For us, that is a significant swing and many many guests contact us requesting a special price we have for just a couple of days that is almost half of what our "normal" price is. For example, right now, my listing is showing a price of $225 per night, when 98% of our other nights are priced at $399.
Airbnb, can you please give US the option to set this display price, or at least show our standard price instead of automatically choosing the cheapest price over the entire next calendar year?
