Gesture sensitivity is gone for the old gestures in One UI 6.1
Why'd Samsung get rid of this? The old gesture is much harder to register when using a phone case while the gesture hint is hidden. I have to turn on gesture hints for the old gestures to be usable for me. Hoping they'll add it back in Navstar.
FOUND A FIX: Go to Good Lock > Home Up > Task Changer > scroll all the way to the bottom to "Bottom gestures sensitivity setting" > Turn on the toggle and adjust the sensitivity. (I set mine all the way to 100%.)
I can finally comfortably use old nav gestures without gesture hints just like before.
