Board Game Arena

I've played a few times and there has been a change in the screen. It used to have player "boards" on left and the tile selections beside them. Now my board is on top, tile selections beneath and other players below that. I'm having to scroll all over the place to see what is going on. I haven't been able to find a setting "switch". Is there a way to change/fix this?

This is determined by your browser window width, not a player preference. If >=1800px, then you will see the "side-by-side" layout else the top-to-bottom one. Note that your browser zoom will also impact this. I.e. if your screen is just too small, you could zoom out a bit to force a different layout.
