Just updated to this latest version and centering of icons on my middle monitor still doesn't work.
Left Monitor (2560x1440) = Centered As expected
Centre monitor Main (3440x1440) = icons stay on the left no matter what
Right monitor (2560x1440) = centered as expected
With this latest version even a re-install doesnt fix it anymore (at least until a reboot) and the icons are stuck to the left on my main monitor
Win 10 Pro Build 19043.1288
No other taskbar related control software installed except for other object desktop software.
For the time being I have switched back to using taskbarX as that at least works consistently.
If there is any more information I can provide that would help identify the cause of this issue please let me know.
