Did you try to left click on the Brightness & Color configures the Configure Brightness. It should open a popup window 

That Configure Brightness & Color configures the Configure Brightness & Color widget (not the screen brightness. It sound wrong though, but that's another issue) and it's ok to only an option to modify the keyboard shortcut

Oh I see, thanks.

It is a little different when I hover my mouse over the tray icon now 

I can scroll up or down with mousewheel, or left click to adjust screen brightness (Brightness & Color pop up, then a slider for 'Display Brightness').

This doesn't actually adjust screen brightness on any of my 3 screens, but I do get an on-screen visual indicator of brightness going up or down at 5% increments (this did not happen previously), but the actual brightness does not change on any of my 3 screens.

(PS - I can confirm that middle-mouse-button click suspends and enables night-light on all 3 screens)

Hope that helps,

I can't see how to edit my previous, but have added 2 screen shots

Brightness Visual Indicator (what I see on-screen when hovering over tray icon for Screen Brightness / Nightlight & scrolling my mouse wheel up/down)

Display Brightness Pop up slider - the window that appears when I left-click the tray icon (I don't recall the slider for brightness being available previously - maybe I just missed that?)

Sorry, I can't help you further. There is work planned for Plasma 6.2.0 that would allow user to change brightness for multiple monitors individually. Would that fix your issue, I don't know.

I'll move ticket back to reported and someone smarter can jump in.

Roger, no problem, I'll just document what I find here.

It has changed back again today, now there is no 'scroll to change brightness' when I hover over the brightness/night mode icon in the tray.
