I have the same issue, no combination of zones, sensitivity, angle wedges, corner wedges has helped. If I create a small zone, very tight, it helps a bit but then I don’t receive notifications when someone pulls into my driveway. I had to resign myself to manually setting it to People Only in the evenings. Wouldn’t be so bad if you can set People Only on a schedule like the Motion Scheduling but you cannot.
This issue is not isolated to Ring devices, it’s an issue with the technology as other manufacturers suffer from the same issue.
