Hi @Ka-Chun0
There seems to be an ongoing issue with the Booking.com link import to Airbnb. I have had issues intermittently with syncing calendars on Vrbo. There is another recent thread regarding this problem with Booking.com syncing. A couple of things to try:
On a laptop computer (not phone)
- Use a different browser than you have been using and try it again. If that doesn't work
- Instead of copying and pasting link try manually inputting it character-by-character
If this still doesn't work, I would take screen shots of the error message and contact Airbnb regarding the issue. It took about a week to get this resolved when I had the issue with Vrbo. Send the screen shots to Airbnb.
