Arlo Camera Support Stopped Working

I’m not sure if this is the correct category sorry if I’m mistaken. It is about the Aarlo camera integration available in HACS.
A month or two ago my Arlo camera binary sensors stopped working. I noticed this when the Homa Assistant automations I had that were triggered by camera motion detection stopped working. Subsequently (other reasons) I bought 3 more cameras. The new cameras show up in the HA Arlo camera count, and I see the images (both still and slowly streaming) for both old and new cameras in the HA GUI, but the new cameras show up as not connected. Any thoughts on this? I really liked having the HA integration of my Arlo cameras working. Perhaps some config change I’m not aware of? I think I have logging turned on but I see no log entries for the connections or binary sensors.
Thanks.

Try adding backend: sse under aarlo: in configuration.yaml. The transition to MQTT caused some breakage.

Thank you, Rob, this is fantastic. Everything is working, again.
