Fresco grid position HELP

[gsv3]

I want to make a grid of 48px in a 1296x720 canvas on the iPad app. However, the grid is aligned in the center, so the squares all around the borders are cut in half. I want to reposition the grid to get 48px squares through the whole canvas.

It works in Clip Studio Paint but not on the Fresco app.
