Hello for the logitech spotlight, there seems to be a bug when using multiple screens and the secondary screen is in full screen for some application like chrome that's in a slides presentation. When you have selected the application on the second screen that is in full screen, this is when the bug occurs. I will try to switch between the spotlight, to laser, to magnifier by double clicking. However, when doing this the spotlight will switch to the next toggle but then automatically go back to the previous setting of the toggle, thus always stuck in the initial setting. Impossible to use this feature at the moment.
