Doorbell suddenly missing motion and nothing has changed

My boyfriend takes a walk every morning at the same time, and the driveway Ring doorbell - it always picked him up, leaving and returning. The RSI has been the same for over a year From when we first got the doorbell and if I scroll through, I could see where I see him coming and going, but it’s not detecting. I have rebooted our router and our Netgear Orbi satellite, and there is no signal issue. It obviously is the doorbell, before I buy a protection plan I would like to see what rings response is. Our other Ring doorbell captures everything and that signal is weaker than the one in our driveway.
