I have 4 different computers, I am currently running 1809 on my desktop and 2 laptops and running Windows 10 Version 1703 on another laptop. the laptop running 1703 work as it should. The three that are running 1809 all fail in exactly the same way. I would say that it is a bug that Microsoft introduced/reintroduced when 1803 was released and not a hardware/firmware problem. If I restore my desktop to a version before 1803 it works as it should.
I find it a bit insulting that Microsoft is totally ignoring all of these comments!
