Product categories in home

is it possible show more than 3 categories thumbnail in home?
I tryed to increase to 4 the number in the customizer but I still have 3

…if I decrease it works



It won’t show if the categories don’t have products in them.

Ok, I added a product and it works
is it possible reduce the thumbnail in order to have all categories on 1 row?

thanks a lot

can we add pictures on the categories “boxes” because I only see grey boxes with the names of the categories and can’t figure out how to customize the background of the boxes
