Move object in perspective not possible with snapping active?

[verty (Wolfgang)]

Scene units set to metrics, size to cm and units scale to 0.1
By this I have a grid with 1 mm and 1 cm divisions.

In e.g. top view I see the grid and can use object move with snapping to grid.
All is good.

But in persepective view there is no grid and moving the object does not work.

Is there a way to enable object movement in perspective view in this case?

You can only snap where grid is, set a finer grid in the overlay settings:

That did the trick. Thanks
