Hope you can help. Most of the time the doorbell works fine; this is an intermittent issue. Motion detection works - I have video of someone approaching the door; the chime activates with motion detected in this case ; it is shown in the timeline as a "Person Detected" event and I can play back the video. As I watch the video playback I see my Amazon delivery driver press the doorbell, you hear the bell make a noise so they know they have pressed it. However... We get no ring alert, the chime does not activate and nothing appears in the event history; either as a "Ring" or "Missed Ring" event. This is a pretty fundemental failure... it does everything it is meant to do EXCEPT the basic function of a doorbell to tell you when someone has pressed the button. We only answered the door when we heard them knocking as we assumed the motion event was a false positive or someone just posting something. Most of the time it works as expected but if it cannot be relied upon it is effectively useless. I have noticed it happen twice in one day with the same Amazon delivery driver... do they have weird fingers or something. I can priovide the event log, the video "evidence" or anything else. I tend to participate ion a lot of teh Ring Beta Testing, so the firmware is up to date, sowfatre is up to date, I have validated signal strengths, etc, etc.
