Question on Edge Scrolling and Centering on soldier

I am trying this game through Gamepass, and I can edge scroll left, right and down but NOT UP moving the mouse. Apparently I’m not alone. Why?
Also-when I have a soldier selected and scroll the battlefield, I have no idea how to re-center the camera on the selected soldier. Clicking on the portrait opens up in screen etc. I wind up hitting tab constantly just to get back to the group and tab through till I’m on the same soldier again. There must be a more intuitive way to do this. Left OR right clicking on a portrait both do same opening of the character screen.
There are very few key bindings and some of them are not allowed to be remapped. Shouldn’t this be available?
