Unifi Smart Detections stopped working

I have 2 UNVR's and 2 C8 Hubs using the Hubitat built-in app for Unifi Protect. Smart detections stopped working on all of the camera's on both systems on Friday. It does report basic motion events and isDark events, but SmartType detections have stopped.

The Comm status is "good. i have rebooted everything and everything - both the UNVR's and the C-8's are on the latest versions. In the logs the Websocket status is "Open" currently.

Thanks for any help.

Are you sure you're using the built-in integration? It doesn't report anything that sounds like either of these.

Sorry, I was mistaken - it's the "Unifi Protect Controller" App by tomw.
