I have the ring doorbell 4 and for the most part it is what I expected. I am surprised however to find that UPS and FedEx do not seem to get picked up. I have deliveries made, driver walking directly at and packages dropped right under the camera yet no recording of it. Sometimes I will get them climbing back into their truck and leaving however that is rare. It appears from online research that I'm not the only one however I have not seen any real answer on why this is or how to resolve it. Any advice?
