Issue with delay in recording - only get recordings of people walking away

Seems that I can't ever get the recording of a person walking up to the door - only away, which is sort of useless footage. This is a battery powered ring video doorbell 2. I live on a busy street so I have people only mode on, motion sensitivity is right at about half way on the scroller, and I've got advanced motion detection on (so it doesn't include the street). It's a straight shot from my front door to the street, with a walkway connecting my house to the curb - I'm a tall guy and it's a full 15-16 steps to get from street to door on the walkway.
