This has happened three times to me now. The last time this happened I requested to book an airbnb in Mendoza from January 26th through February 1st. I then insta-booked another airbnb in Mendoza from February 1st to February 8th. When I insta-booked there was a checkbox to notify other hosts that you don't need accommodation for these dates anymore. I specifically unchecked the checkbox, but Airbnb went ahead and incorrectly added a message to my first booking request that I no longer needed the airbnb for these dates.
Not only are the reservations non-overlapping (checking out February 1st and checking-in Feburary 1st at another airbnb is not overlapping), but the site didn't even care that I had unchecked the checkbox, and it went ahead and erroneously messaged another host.
It'd be great if you guys could fix this!
