Ring Camera and Amazon Deliveries

Recently, we noticed our Amazon deliveries are not showing up on our Ring cameras. This was confirmed today. I was home and watched the Amazon Delivery person walk up to our front door where one of our two Ring Cameras are located. He set the package on the step and took a picture of the package...literally in front of the camera. I went outside 2 minutes later to grab the package and my Ring Camera picked me up. How is this happening? Wifi Blocker? I am not spending the money to hard wire. If Ring can't solve this problem, we will need to disable our service and find another security camera that has the capability to not be blocked.
