My understanding is they are both dimmable. The vague guide I was following is this:

In terms of dimmer/driver placement, I originally wondered about this, but the thread linked to above states it goes mains → dimmer → driver → LEDs. Looking on the back of my dimmer switch, it does say 230V AC, which surely means it would require to be before the driver? If it was placed after the driver it would be getting 12V DC?
The switch is obviously more than just a potentiometer, it has all the ‘smart’ stuff in it, which presumably is set up to work with the power listed on the back (230V AC)?
I have ordered another dimmer which I will test tonight, it may give a clue to whether the fault is with the dimmer, or the LEDs/driver/order of components. I am trying this one next:
