Swipe Between Messages

Hi team. This is probably a dumb quick fix…

I used to be able to swipe up and down between messages in the MacOS Messages app using 3 fingers on the trackpad. This was the case on my MacBook Pro’s in recent years. I’m using my wife’s MacBook now and it doesn’t seem to work.

I didn’t think this was a tweak I’d set up, but does anyone know how to get it working? I’ve checked all my trackpad settings. I’ve checked BetterTouchTool and BetterSnapTool to see if I had it going in there too.

Any ideas?
