Hello,
The thing is, we’ve noticed that your staging site has Rich Text Editor support enabled in the Category Description area. However, this is not available by default with the theme — as confirmed on our test environment.
Here’s a screenshot for reference: https://ibb.co/Gfx1D7JY
To enable the same functionality on your live site, we recommend using a plugin such as:
https://wordpress.org/plugins/rich-text-editor-tinymce-for-woocommerce/
This plugin should allow you to use the visual editor in category descriptions, similar to what you’re seeing in your staging environment.
Best Regards,
