Problem:

The user essentially wanted to add a Next Product button to their product template

Solution:

Assuming that you are using a custom Woocommerce template created with the Block editor, then there isn't a block for this. However you can make use of our shortcode base solution to achieve this.

Take a look at the link below for documentation on the Next and Previous shortcode.

You can use the gutenburg shortcode block to add these shortcodes to your custom product template.
