GeneratePress + WooCommerce + SiteOrigin Pagebuilder

Hello,

I am using GeneratePress + WooCommerce + SiteOrigin Pagebuilder

Everything works great but i need to fix the mobile display of my homepage.

In homepage i display some collections with "products columns="3".

In big screen it works great, but in mobile view it shows the product in 2 columns
while i need to show them in 1 column.

I tried to used the woocommerce setting but it only works on products page and not in the homepage.

Any ideas??

Many thanks in advance
