Problems with calendar sync with my Gmail calendar
I seldom login to booking.com coz majority of my bookings come from Airbnb. However today I received a booking but my place has already been booked and I have already setup my booking.com account to sync with my gmail account calendar.
I have updated that my calendar is not available.
How is it that booking.com does not sync to my gmail calendar automatically?
Do I need to login to booking.com and press the sync button all the time?
