Random not working in woocomerce shortcode?

Question

WordPress

I insert a shortcode

[products orderby="rand" order="rand"  attribute="stil" terms="Дизайнерский" per_page="8"]

The task is to display products by attribute style (a certain style of design) 8 items per page and constantly display randomly when updating. But no matter how much you update, the products are displayed the same.
does orderby="rand" order="rand" not work?
