Hello 👋 this is your personal demo site. You can test how permalinks for products and categories can be adjusted from here. Note, that extra folder after domain (eg, /jybmgr10ipzeo5h/) is an identification of the demo, that folder will be missing on live setup.
Go to wp-admin panel (toolbar above) and then WooCommerce > Settings > Custom Permalinks to find product and category permalinks variations.
