Sirens not sounding

[ajmorr-is]

I have two Arlo cameras integrated using this great integration, and I'm not able to get either of the sirens to trigger via HA on the individual cameras switch.aarlo_siren_driveway_cam/ switch.aarlo_siren_garden_cam or using switch.aarlo_all_sirens. When I trigger the sirens using the Arlo app they work as expected and in HA the switches then show instantly as on/off including all_sirens when both are fired together.

Any ideas?
