Just an FYI of something I saw. I have not yet reported this issue to airbnb.
I have a weekend premium priced using an airbnb rule. “83% nightly price increase”. Someone booked my dates with 1 guest. All is good with pricing at this point (I charge the same amount for the unit no matter how many guests they have - they just cannot exceed my guest limit)
The guest requested an alteration to change to 3 guests. Airbnb took my pricing back down to the BASE pricing when the guest requested the alteration!!!
I obviously declined the alteration! But, the guest noticed also ans asked about it, so I had to explain my pricing…
I started an alteration from my side also, and saw the SAME thing! It was reduced down to BASE pricing!
