Notifications you will not get
Some things produce no notification, and they are worth knowing.
There is no notification that a space has become free. A cancelled booking releases the dates, but somebody who was looking for them earlier is not told — it is worth checking the search.
What you did yourself does not come back to you as a notification. If you cancelled a booking, the other side is notified and you are not.
There are no notification settings. There is no mute switch and no choice by type. Everything written appears in the bell.
A notification pointing at a listing or a conversation that no longer exists disappears with it.
