Virtual desktop scroll with mouse not working since upgrade to Kubuntu 21.04

Previously I was running Kubuntu 20.04 (and many versions before that) and I've had center roller mouse scrolling across 6 virtual desktops working for literally years. Yesterday I upgraded to 21.04 and it no longer works. I've been diving through System Settings looking for the control but cannot find it.

Workspace Behaviour -> Virtual Desktops (no)

Input Devices -> Mouse (no)

Can someone point me to where this setting exists?

Thanks

To anyone who runs across this in the future. The problem (most likely a bug) is that it's not working when the desktop is configured in 'Folder View'. Switching to 'Desktop View' resolves the problem.

Right click on your desktop. Choose (as appropriate for your version of KDE) either 'Configure Desktop' or 'Configure Desktop and Wallpaper'.In the LAyout choice choose 'Desktop'.

Hope this helps.
