Hello, just wanted to say that I had the same issue. Decided to give One UI Home a try because of the expanded folder but when I press and hold the folder, I don't get the expanded options. When trying to delete apps from the home screen, no options there too.
Anyway, I figured out that you have to set One UI Home as your Default Home App. Since you have Nova Launcher like me, long press Nova Settings icon, App Info and look for Home screen. Change it to One UI Home. After that, you should get the 'extra' options.
Hope this helps.
