How do I get Cut snapping back?

I assume this is a change of one of the newer updates give it just suddenly changed.
So what I mean by Cut snapping is before if you zoom in to the maximum in your timeline the cut tool would snap to the space in between the frames which makes sense given you cant cut halthway in a frame but now this is not the case anymore now it just moves entirely freely and ignores this frame based grid.
How can I revert this change I really cant work like this
