I enabled ADB in the instrument menu on my MY21.5 but it doesn't work, still only normal high and low beam when over 40 kph.
Has anyone else had ADB not working?

Are you saying you get the blue head light icon (ie ADB activated) on the dash but no adaptive beam control functionality or are you saying you only get the white and green head light icons on the dash even though you have activated ADB via the instrument controls.
Note, I assuming everything is the same between the RRS - ADB and the RR - ADB, if above doesn't make sense then maybe there is a difference.

User error - it wasn't quite dark enough! High beam wasn't coming on above 40 kph on my un-lit driveway yet the lights were in auto and ADB was set in the instrument cluster. But now properly dark, high beam comes on. I like that using manual high beam until over 40 kph then flicking the lever forwards results in a seamless change to ADB.
I'm looking forward to seeing the left side of the road lit with oncoming traffic when previously on low beam it was un-lit. Unfortunately LR don't think there's a need to throw much light out to the verges so it's dark near the vehicle and virtually no light on the far side of the road unless on my gravel single lane road, but which has nothing to do with ADB. I'm heading towards fitting driving lights and hope to have them on in manual high beam mode but not in auto/ADB mode, but it's early days in my canbus education. Plan B would be to fit a $200 canbus high beam module and to use the relay switch rather than the standard light stalk to control the driving lights.

What's also good is when you're following behind someone then the beam is actively and continuously shaped to throw light down both sides of the vehicle in front but blocked from shining into their rear window / rear view mirror.

So I've read, but have yet to experience. I'm always conscious of my lights glaring vehicles ahead so drop to low beam when I could really do with more light. I've also read that quite a few people regard the feature as the best feature of their later model RR/LR. Maybe it will make-up for some of the annoyances of this vehicle.
