I had the same issue and also noticed that the amount due to me was not marked paid out in the transaction history, nor was it in future payments.
I got onto airbnb and was told that the transfer had been made but it wasnt marked paid out as they had two steps, 1. They sent the money. 2. They waited for a response from my bank and marked the money as paid out. They suggested that I wait until today and the status has changed.
I had not received the email but did this morning. I think they have changed their process although they didnt say so and now wait also to sent the email until they get the bank response. The email used to be sent when they sent the money (24 hours approx after checkin).
I think that it is foolish to make these kind of changes without telling hosts as we cant be the only two people who contacted support
