1. Make sure you have the mirror selector on the driver's door set to the passenger side (left for UK or RHD, right for EU/LHD). Any other position and it won't dip. There is also a setting in the infotainment under Car > Settings > Mirrors (I think, but somewhere like that) where the option can be disabled - worth checking it is still turned on.
2. FWD afaik, or at least front-biased - it's a Haldex 5th Gen system. There's quite a good video of the Kodiaq Scout going off-road at the link below where you can see the rear wheels driving (watch from 26:25 into the video for an explanation), but they only get torque when the fronts start to slip (in a simplistic terms, but it's probably a good bit more complicated than that!):
