Cruise Control not working

Hey all,
Is there anybody in here who has had any issues with the Mavic 3 Cruise Control not working at all?

A few months ago now, I tried to use this function in a test flight but the stick settings did not lock at all…
I use the standard RC-N1 controller, which make the activation of the Cruise Control with the Fn Button somewhat difficult to say the least. I honestly pondered whether to use my teeth or not…

I managed to push the button, but nothing happended.

Any thoughts.
