Three-finger lookup is not working after updating to "Big Sur"

The lookup function worked well before I updated to the new MacOS "Big Sur", and I didn't change any setting of it. How should I do to fix that? (Btw, it's also not working after I changed to "Force Click with one finger")

I've just run into a similar problem myself.


It took me a while to work this out, but it looks like the "three finger lookup" conflicts with Accessibility Zoom feature (aka three finger double-tap), if that is enabled.


For me, "three finger lookup" started working perfectly as soon as I've disabled:


Accessibility > Zoom > Advanced > Controls > Use trackpad gesture to zoom
