I installed two Ikonic Fellino privacy door levers. Door handles seems to function correctly and door bolt correctly engages with the latch.
However, in both cases the privacy function does not work. When I push the button in and then try the external lever, I can feel a tiny bit of resistance but the door opens and the button pops outwards.
I could not see anything in the install instructions related to the privacy button.
What have I done wrong?
