Magic Trackpad weirdness on iPad springboard

Issue: Using the Apple Magic Trackpad 2 (external bluetooth) when swiping between the pages of Springboard on iPadOS, I need to use a two-finger swipe UP/DOWN instead of RIGHT/LEFT. I find this really unintuitive, and am constantly triggering the “Search” that is usually the “the two-finger swipe down”.

Not sure when this changes, but it’t quite recent (iOS 16.x).

I’ve been looking for a setting to revert to the default behaviour, but am coming up short. Anyone else notice this and know how to stop this madness?
