How to working with polar grids in kicad

pls help me how to working with polar grids componenet placement in kicad. i am selecting polar coordinates option but the pcbnew still in cartesian coordinates view

Look to the bottom of the window… notification area… the relative coordinates (not the absolute ones) are switched to polar.
That’s all I see that does look polar to me.
It will still snap to the Cartesian coordinates though…
