Hi @Emma3573 ,
I'm a bit confused.
Is it your valid phone number and you are frustrated that the AIRBnB APP is telling you it is already use? Or you want your phone number removed from your profile.
I was looking at my app.and I think phone number is only on the Traveler side not the host.
Have your tried and call AirBnB support? If you d use the traveler side for support and not the guest with the telephone prompts.
Hope that helps and the best of luck!
