syncing with Booking.com seems to work well. My only concern is that it seems to take about an hour for the booking.com reservation to show up on my AIrbnb calendar. I'm concerned that I might get a conflict if someone books those dates in AIrbnb before the AIrbnb claendar has been updated with the Booking reservation.
Is there a way to force the sync so that the AIrbnb calendar updates quicker?
I'm glad to hear that overall it's all working quite well for you! I found some additional information on this functionality here, that might answer your question:
Your Airbnb calendar automatically resyncs every five minutes, although the frequency of resyncs by your external calendars is determined by their owners (e.g. HomeAway or Vrbo).
