I am going through the same issue which is very frustrating. The device health works on my android phone but not on my PC app for Ring doorbell and camera.
I have reset the Ring app but to no avail. I have tried other methods thru youtube but again to no avail.
I am going to call Ring customer service to determine what the problem may be and if they can help.
By the way, I installed the latest version of windows 10 this morning which is 1909 and it may be that may be the problem but I do not know because the device health was working before in upgraded to windows 1909.
