I'm using the K380S keyboard. When I enable the function keys as default using FN + ESC, the 'Ins' key, which also serves as the volume up button, doesn't change its behavior.
With the previous K380 keyboard, the 'Ins' (volume up) key also switched when changing the function key behavior. It's quite inconvenient that this doesn't work the same way on the K380S.
I'm wondering if this behavior on the K380S was intentionally designed, or if it might be a bug?
