Hi @Bhumika,
Unfortunately, I had to solve it on my own without an adequate help from airbnb support. It was all about new update features. Without giving detailed explanations of how to adjust custom trip length with new "rules set", how would I be able to know how to do it...
Previously, on calendar part, I was able to select the dates and put trip length on whichever I wanted. Now, we are required to put "rule set" first, then apply these on the dates that we wish to adjust their trip lengths.
I guess this part deserves better explanation from airbnb side...
Sincerely,
Gokhan
