@BMunn205 I've been getting "quality updates" to the version I was on.  But have still not done the Feature update to 20H2.  Just checking Windows Update and it says "Your version of Windows 10 will stop receiving important quality updates soon.  You can stay in support by updating to a newer version of Windows 10."  This is underneath the section on "Feature Update to Windows 10, version 20H2".

So it sounds like I am going to be forced to try it again soon.
