We believe this incident is related with delays on Airbnb's side.
The validation of instant bookings appears to be delayed, causing "new reservation" messages to be themselves delayed, while the status of conversations appears as "not possible" in the meantime.
Opening the conversation on Airbnb or Smartbnb may trigger the new reservation to still be sent within one minute. Scheduled messages would still be scheduled, but we recommend affected customers to reach out to us, with the confirmation code of affected bookings.
No other bookings events appear to be affected by this incident.

We are investigating a possible incident with Airbnb triggering "not possible" events immediately after the booking is accepted.

We are currently investigating an incident with multiple booking confirmation not being sent.
