I'm trying to create a 7-day rolling window where no bookings can occur so I have at least 7 days to fulfill a booking. It appears the "Advanced settings" should allow this, but it doesn't seem to work. I set "Reservations must be made latest:" to 7 days by 6:00am and when I go to the website it will let me book an item for rent any day in the future, including the 7 days that I've blocked. I'm not sure what I'm doing wrong.
