found it out, You can click the view tab, and there’s a new option called “Selection Styles”. If you click on it there’s an option to revert it back to bounding boxes.
You can go to “Studio Settings” then type in the search bar “Select” and under the studio tab you will see “Selection Box Thickness”. Change this to anything (iv set mine to 4) and it makes the outline much easier to see and much like the old style.
Your also able to do the same for “Hover box thickness”. Iv set mine to 2.
