Why is Motion Warning not Working on Wired Floodlight Cam Pro?

So far I am sooooo unhappy with my first Ring product, which is the Wired Floodlight Cam Pro. I already have a post about the fact that the motion lights go off every 30 seconds all freaking night with no motion and the camera does not record any motion of what is setting the lights off. I have another camera system to verify there is no motion, but I digress. So now I see there is a new option of “Motion Warning.” I wondered what that was and saw it speaks a message when it detects motion to tell the possible person they are being recorded and it only works on certain devices and they must be wired. Well my Wired Flood light Cam Pro is on the list of supported devices. The option is there. When I turn the option on, it gives me a message saying, “This Ring Device Doesn’t Support Motion Warning.” It goes on to say if it is not working on a supported device then to make sure I have the latest app.. I have a supported device and the latest app. It does not work. Nothing with this very expensive camera seems to work! What is the deal with things not working right on one of your newest and most expensive devices? This is unbelievable.
