Calendar syncing error
I have a problem. My listing is on Airbnb and Booking.com. I use iCal to sync the calendars, and it has been working fine. Until, that is, I discovered one booking made on Airbnb that did not appear on Booking.com. When I discovered it, I created a test booking on Airbnb, updated the calendars, and the test booking appeared on Booking.com, so the error was for this one booking. Of course, somebody then booked for the same dates on booking.com, and it was some time before I spotted it. The Airbnb booking came in first, I explained this to the Booking.com guest, and they have now cancelled. The fact remains, I cannot rely on calendar syncing. Has anybody had this problem, and what can I do?
