How to enable 'Never Combine taskbar buttons'. Windows 11 ?

Edit 2: I realized later that this is related to a different expected functionality, but still can be useful to some, less grouping at least!

Hello,

I think they changed the text for this function into another text in the settings.

Go to "System" > "Multitasking" > "Snap windows". (In fact I have accessed this by right clicking the group in the taskbar and choosing "Group settings")

There is a checkbox for the option: "Show snap layouts that the app is part of when I hover over the taskbar buttons"
Unchecking this did the trick to me.

I hope it helps!
Cheers

Edit: You can access these settings by searching by "snap settings" in Start.
