I have the 2022 versions of the soundbar, sub and rears, to be honest the instructions are pitiful and even online forums mention nothing.
Personally if you have the matching Samsung TV then just pick the intelligent setting, spacefit, etc... the Smartthings app gives a little more control, but beyond that your are down to a tiny led screen on the soundbar, to change levels of the sub and rears.
