Hi. I have had problems with my Ring door Pro for about a week and a half. When someone presses the button and you open the app in the phone (Iphone x and Iphone 8) and receive the call, it just grunts and hums, it sounds like a tractor is running right next to the bell. You can not talk in it. And it sounds the same in both the bell and the app. Same sound. But there is nothing wrong with the actual video part the image is as usual. So I thought it was wrong on the device so I bought a new one yesterday. Exactly the same problem with it. So I thought if there was something in my network that did it so I have moved the stuff from my solid fiber to a 4G router. Gets exactly the same error.
Have had the products for a little over 2 years and never had these problems before.
