Night shift only working on main external display, not others

[doobydoooby]

Anyone else with multiple external displays able to confirm if this is a general bug? I have night shift enabled, I have two identical external displays, each connected by the same method to my mac pro. Night shift works on the main display but the second display, which is used as an extended display, is 100% bright no matter what night shift setting is on.... any changing of the settings for Night Shift changes the main display buit makes no adjustments whatsoever to the second display...kinda weird....

OS Monterey 12.2, Mac Pro 2020

For some very strange reasons Apple officialy supports Night Shift on few external monitors:

Use Night Shift on your Mac - Apple Support

Night Shift automatically shifts the colors of your display to the warmer end of the color spectrum after dark.

I had similar issue and gave up fighting with Apple Night Shift implementation - I went back to https://justgetflux.com/ which I used for many years before.

Well, in my case the two external monitors are identical. The primary one is working with night shift and the other, the extended display, doesn't. If I switch which display I use as the primary and extended displays, then night shift always works with the primary one, so it seems to be entirely down to an OS issue. Both worked fine in tandem in Big Sur with Night Shift

And indeed, before night shift was doing its thing I did use flux, maybe I go back there again. Thanks for reminding me!
