Hello,

1. Have you configured any custom URLs in Settings > Permalinks? Try to save permalinks or set back the initial configuration and check.

2. Yes, there is the option to add a tab individually to each product, create an HTML block and insert its ID shortcode into the Additional tab field https://xtemos.com/docs/woodmart/product-page-options/#local_settings

If you need further help, please let me know.

Best Regards
