Resolve 9 Scene Cut Detection - slower to use than 8

Scene cut detection seems much slower when editing now. I figured out that I could use the + and - key to add or delete cut points, but why do I have to click on play screen to activate the left and right arrow? Is there a keyboard shortcut? We use a lot of transitions that scene cut detection doesn't mark correctly, and adding and subtracting cut points just seems much, much slower now. Any advice or comments?

Use the N and P keys to go to Next and Previous.
