Change Default Sorting on Main Product Catalogue

[King_EJ]

Currently, the way the default product catalogue is sorted is by A-Z.
I want to change the default sorting to the newest products first. AKA "'created-descending'"

I've tried editing a bit of code on the "main-collection-product-grid.liquid", specifically:

// tried changing the default in this code to a few different options.

{%- assign sort_by = collection.sort_by | default: collection.default_sort_by -%}

// Added the below code as well.
{% if collection.handle == "all" %}
{% assign sort_by = 'created-descending' %}
{% endif %}

Please advise how to change the default sorting of the main product catalogue

1. In the theme editor, navigate to the "Sections" folder and open the main-collection-product-grid.liquid file.

2. Look for the following code:

{%- assign sort_by = collection.sort_by | default: collection.default_sort_by -%}

Thanks for the reply Nomtech!

I have already messed with that code to no avail.

I'm sure it's the right line of code to change but I dont know what to change it to, in order to default it by product upload date.

I probably change this part, yea? "default: collection.default_sort_by"

To what?
