I changed my banking details, while 2 payments were coming to me.
I don't think I got them now. I cannot see that I got them.
I am worried that because I changed my banking info during the time that money was "on way" that it disrupted the process somehow and now the money is lost.
Hl... first just check with your old bank whether the have received the payments and are holding them in your closed account. That happens in some countries.
More likely, if your account was closed, the payments will be sent back to AirBnB - although this could take some time.
