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
