@Kelli33 the discount should be applied when the booking is made: you shouldnt need to do anything.
Click on the reservation details: it will give you the amount of payout. If it still seems wrong I would call Airbnb before speaking to the guest about it.
Hi Matthew - I posted my home for the first time this weekend and this weekend I got my first booking. Because it's only been maybe two days and she is my first booking - she is entitled to the 20%.
I will be trying to reach AirNB to discuss it with them.
