I found an answer that worked for me. Try the following
In Explorer, click on the
- three dots on the top bar, ie "..."
- then Options
- then View
- Scroll to the bottom to Advanced Setting
- Under Navigation, only check boxes for Show Network and Show This PC. Keep others in Navigation unchecked
When I did this, I was able to arrange all folder in Quick Access/Home as usual
The issue was that I had the Show All Folders and Show all Libraries checked, for some reason that takes away the ability to rearrange folders in quick Access.
Good luck!
