Recently my Ring Doorbell 2 stopped registering if someone pushes the ring button:
ring event not registered in the app
This seems to be related to motion detection triggering shortly before the ring button is pressed. For now, as a workaround I have disabled motion detection.
I did not have motion notifications enabled, only the detection.
I already tried restarting / resetting the Ring Doorbell 2, without success.
No changes were made to my network, or to the settings of the Ring Doorbell 2 shortly before the issue started occuring. It has been working fine for over a year, combining motion detection and ring alerts without problems.
