Superb 4 kessy problem

When setting up kessy, it doesn't respond to opening the door. It's happened to me once and then it started working again out of nowhere.

when I set the door to open when approaching, it always works, but this option doesn't suit me. When I press the button on the key handle(nfc)the car locks, but if I want to open the doors, they don't unlock.

Does anyone have the same problem or have any advice on how to reset or "fix" it? turning the kessy option on/off doesn't solve the problem.
