I've been a host for a couple years, but just started using Instant Book. I selected the allow guests with positive reviews option, but just had a guest with no reviews book. Is this a bug or am I misunderstanding something?
I think it is an intended bug - I had the same issue with a recent booking. Now you are left with going through with the booking or cancel and face the penalties.
I am new to Airbnb and I also have ticked the box for only accepting guests with review on instant booking . In my first five bookings 3 have not had reviews and one does not even have a photo. It all went pear shaped today when we went to the house to prepare it for the next guests. It was filthy and had clearly been used for a party. Breaking one of the rules.
