I'm using Narrative theme for my store: https://tribalmine.com.au/ and am hoping to alter the number of columns when displaying products on a Collections page, e.g. https://tribalmine.com.au/collections/grounded
The default is two columns on desktop-view and one column for mobile-view. Each product is HUGE and it means a lot of scrolling for the user.
I wish to increase this to three columns for desktop and two for mobile.
Assistance greatly appreciated.
