@Susan1188 , well said, those of us like @John2654 and me that have a flex policy have always known we can and will lose bookings up to 24 hours before first available check in time and accept that because of the benefits you stated above.
One clarification, people cancelled because Airbnb didnt create an "EC" Button, its not actually a traditional cancellation. Most didn't want to cancel, they just couldn't do the trip for one or more of 20 legally acceptable reasons that were completely beyond their control. Keeping the guests money at that point would have been theft.
No matter what policy we all had, no policy can override a catastrophic situation like this, its the epitome of "Extenuating Circumstances. The fact that Airbnb is giving anything to hosts is more than they probably have to do considering they already refunded the customer.
Its sad but real and I pray everyone's worst memory of this year are guests that got their money back and hosts that lost money, stay well all, JR
