@Oana-Gabriela0 Usually the glitches that occur in the app aren't replicated in the desktop version, and vice versa. So whichever version of the platform you're using, try switching to the other.
I'm a developer and I tried what you've told me (from PC, Android and Iphone) and I also tried to inspect the errors from "Console - html" to see if I can pass throw.
But without succes. I wrote to Airbnb a message.
If they will answer me, I will post it here. Maybe there are another people in my situation. 🙂
I succeed to figure out why I had this problem. The reservation was done from another account and I was only a member of the reservation. The only person who can cancel / modify it, is the main guest (the person from which account the reservation was performed). 😄
