Adobe Illustrator snap to grid why does the outline snap with a slight inaccuracy?

Question

Design

The question is why, when snapping to the grid is on, the points are not snapped exactly to intersections, and how to solve this?

Answer 1

A constant problem, always some kind of crap with the binding. Sometimes it helps to hold down ctrl

Answer 2

There is such a glitch, I solve it using transform (shift + F8) indicating the dimensions and coordinates. After that, you can already stretch again, etc.
