We are seeing an elevated rate of 404 responses from Booking.com when posting messages on behalf of hosts.
Roughly ~10% of outbound messages to Booking.com are failing: both automated (scheduled and event-based) and manual messages sent from the inbox. The remaining ~90% are sending normally.
This started around May 7, 08:00 UTC. We've reported the issue to Booking.com support and their product team is actively investigating.
