Calender import - not a valid iCal URL
I am trying to sync calenders with Tripadvisor, Airbnb and Homeaway.
Each time booking.com says the are not valid ical URLs. They ahve always worked between each other sites and they are iCal URLs. like this: https://www.airbnb.co.uk/calendar/ical/1050068.ics?s=5670f6116350e62ec725f74ace4ffdf5
Help - can't sync - about to ditch the whole idea. grrrrrr!
