it doesn't work that way, I don't think the exact hour when Airbnb send emails is important
My check out time is at 11 h
My check in time is at 15 h
I get emails from Airbnb at 16:19 to review the guest from UK, it is 5:29 h after check out and 1:19 h after the next check-in.
( UK - Croatia is 1 h difference)
I could leave a review until somewhere between 16:00 - 23:30 , I am not sure when exactly it expired.
I get emails at 14:29 to review the guest from Canada
( Canada - Croatia is 6+ h difference)
I got emails at 7:09 to review someone from my own country.
