Camera notifications inconsistent

Ring Security Cameras - I think the model # is 8SF1P7 - hard-wiredSamsung S8 phone / Samsung Watch3A number of problems beginning a few months ago. I suspect (hope) it is all one problem.Camera lights come on intermittently. No audible/visual notification. No video on the Ring app. Light comes on/goes out as it shouldFor a few hours a day, the Cameras give audible notification and my watch vibrates as it should. Usually late AM. The rest of the time I get a watch vibration or nothing from either deviceInfrequently, I get a watch vibration and the watch displays a still pic from the camera. Nothing audible. Most of the time, just notes which camera sends the notification.All of this is true of all cameras. How do I resolve this?
