How to get "snap to live input" working?

In scale assistant, I’ve checked the box for snap to live input. However, it’s still letting the blacked out keys playback instead of moving the midi input to the correct scale. Any ideas?

The feature I’m talking about is shown at 22:00 https://www.youtube.com/watch?v=LF2lNVE7MbY

Having the same issue!
