Simple plugin that hides the uncategorized / default category from the main shop loop in WooCommerce 3.3+. Just download, install, and activate this plugin. No settings required.
Most (likely all) of these require new hooks to be put into WC core. So will revisit later.
- Hide default category from product meta section.
- Hide default category from widgets.
- Hide default category from the [product_categories] shortcode.
- Hide default category from product permalinks.
