When I established my Airbnb listings, my first property manager was listed as a co-host with the business email and phone number. I need to move that information to my new property manager. (My first property manager is still listed as a back-up co-host.)
From what I see, I would have to remove/delete the first property manager in order to "free up" the business email and phone number that would have to be reassigned to the new property manager. And it would appear that I would have to delete the current property manager and re-establish as the co-host again.
Hope this makes sense.
