Terrible motion detection.

I’ve had the Ring Doorbell for a couple of weeks now and it’s so far been useless. We get notification of “motion” every time a car drives by, but when someone walks into our yard, up our driveway, up onto our porch or right up to our door, we get nothing. If one of us walks out the front door it notifies us that there’s someone at the door, but we get no notifications when people come to the door, like delivery drivers etc. I’ve tweaked the motion zones and sensitivity so many times, I’m not sure what else to do. I don’t care about cars driving by, I care about someone coming into our yard or up onto our porch or to our door. Am I the only one with this issue?
