Same happens to me, have the account for about 3 years and just noticed when sharing the link redirects to home page and says " This listing is no longer available." at the top.
All the settings are correct and it says "You are all caught up".
Wrote to support, waiting for a few days, didn't solve it yet; sent me a link which doesn't work if you are not logged in.
Any tips / suggestions? Should I just delete the whole account and create it anew? That would be the last thing I'd like to do, but will do it if there's no other options. I really need my AirBnb account to work.
Looking forward to any suggestions!
