Ring doesn't detect doorbell being pushed

I've had this happening multiple times already. Delivery guy brings a package, rings the doorbell, the doorbell itself give the ring-tune, but inside nothing is triggered. The chime doesn't give a sound nor does my phone.When I looked in the video recordings I saw that there was motion detected, with a recording of the delivery guy stepping up to my front door, pushing the ring doorbell and you can clearly hear the sound of the Ring. But the video is not marked as "missed", just as motion, which implies they didn't push the button, which they did.Please fix this because it makes this doorbell pretty useless !
