Top Bar in Botiga Theme

Hi, I’ve just updated to the latest verson of the theme and seem to have lost my top bar (ny site is still WIP though).

I’ve followed the instructions here
https://docs.athemes.com/article/enabling-and-configuring-the-top-bar/

“To enable it, go to Customize > Header > Top Bar and click the Enable Top Bar toggle.”

but in the Header section there is no Top Bar option.

Please help me get the top bar back so I can add a “Free Shipping” notice for visitors.

Many thanks
