Linked calendars won't syncronize

[Germán13]

I linked two listings calendars to each other. In both listings' settings they appeared to be linked, but I blocked January 2018 on one of them and that change is not appearing on the other calendar (still showing January as available). Obviously I don't wanna cancel on a guest, mostly because I have instant booking activated. Thanks a lot!

Possibly, @Germán13, you need to write to Airbnb Customer Service. I have tried to convince them many times that this option has not been working properly from the very beginning, and now almost half a year and it still hasn't been improved. Airbnb calendar still doesn't sync properly with anything other and with itself.

I linked my 3 listings & it shows as they are linked but one of them is not.  The check boxes showed the main house with 2 other listings boxes checked.  But when I go to the availablility page it only says "linked to 1 other calendar" not 2.  Can't figured out what's wrong.  Airbnb's web design is horrible.
