After effects snapping not working

I am finding the same thing. When I draw from rectangle tool it doesn't snap ( points or whole shape). When I draw with Pen Tool points and whole snap perfectly. Guides need to be set to snapping of course. Even when Path 1 of the Rect is clicked no snap!  I suggest using the pen tool when making shapes that need to snap. Remember that the outer stroke affects the shape size and position cheers 

I had the same problem. But there is a misunderstanding here.
In the Tutorial she only aligns the first square with the grid. This is possible with the Shape Layer, but not with each new rectangle, because snaping doesn't work when shapes are nested.
So with snapping, only the first rectangle is in the right position - and thats what she recommends.
By pressing the Shift key, the duplicated rectangles can be moved at the same height.

Even in the Tutorial the dublicated Rectangles dont snap. But you have to look very carefully to see this.
 

I'm doing the same tutorial! it's from motion design school. In the tutorial when she did this part: it didn't snape for her ether she said " with the help of its duplicates draw a figure according to the grid". apparently, snaping doesn't work when shapes are nested. what you have to do is eyeball it. Good luck everyone on finishing the course!

This does not seem to have been adequately answered? I am now doing this same tutorial, having same issue. Everything set to "Snap to Grid", create new shape layers, and... nothing. Objects just rest flabbily wherever I set them, no snapping whatsoever.

Try creating the rectangle on a new shape layer.

I am also doing this project, and snapping only worked for me when I created the rectangle on a new shape layer.

We are doing the exact same tutorial, and I am having the exact same issue. 

What. are you trying to snap to the grid. Scale will not snap, Position and Anchor point will.  Vertices and bezier handles will snap.
