I just reinstalled windows 10 after a long while, and when i move my skype from my main to the secondary monitor, the taskbar icon remains with the original skype icon on the main taskbar and a "wundows 10" iconstyle on another.
Any update on this? While not using DF taskbar but using Win10 default taskbar, go to Taskbar settings -> Mutiple Displays -> Show taskbar buttons on -> "Taskbar where window is open", that then places the universal app on the correct monitor without being on the main monitor.
