# Bug Report

### Describe the Bug
Recently, the motion trigger for my Spotlight Cam has stopped firing when motion is detected by the camera. The Ring app detects motion, but it is not passed to the HomeKit motion trigger. This has been going on for a month or so now. I've tried a few different things to reset/remedy this issue with no luck. The camera streams just find to HomeKit.

### To Reproduce
Steps to reproduce the behavior:
 - Setup a Spotlight Cam with Homebridge
 - Create motion in front of the camera
 - Monitor the HomeKit Motion Trigger for the camera and see that it does not activate-- ever.

### Expected behavior
Obviously, the motion trigger should be activating. It used to work just fine until a month or so ago. I have been using the motion trigger for a HomeKit automation for over a year and it only recently stopped working.

### BONUS BUG
Possibly related, I am also no longer able to get Doorbell notifications and HomePod announcements to trigger from my Ring Doorbell despite it all being turned on and the camera streaming just fine to HomeKit.
