it currently doesn't work if you click the Task Changer module while in Good Lock.
What's the specific issue you're having?
EDIT: yes, I'm on OneUI 3.1, Ultra Unlocked
I'm having the same issue as above. Task Manager was working on my S21 Ultra until a few weeks ago, but no longer works. I have it set to display the grid view, but it's still showing the original view. Seems to be working on my wife's regular S21. Has anyone found a solution?
