Remove pre-approval?

According to AirBnB Help, to cancel pre-approval:

Go to your Inbox on
Open the message thread with the guest
Click Remove Pre-approval

Only there is nothing like that on the thread. Does anyone know how?

I called AirBnB regarding this and apparently the Help topic is not current. There is no way to remove pre-approval. However, according to the fellow I talked to, pre-approval is automatically cancelled after 24 hours.
