I think I can still do it - under "listings" where I choose "all listings" and then open the three dots under the settings wheel to the far right (...) and use "duplicate" 😊
I had to write to support (took a while to find the right place where I could send messages) to be able to see this feature!!!
What irritates me is not to be able to make one listing of my house with multiple rooms like was possible in 2014 (I think) and they took out again!! I understand they don't want the big hotels to use Airbnb (some of them do it anyways) but I have a farmhouse where I rent out my six extra rooms since I live alone and like both the company of my guests as well as the extra income. My place is as personal as a homestay B&B can be, but it's very inconvenient to have six listings - also for my customers that sometimes don't find the suitable room for them cause they don't look the whole list through!!!
I hope someone sees this who can make an influence to change this again!!
