A "Favourites" section is available within the frontend dashboard page. From here, users can see and manage their favourites.
If the "Favourites" section isn't available, you may have replaced the default dashboard menu items.
Navigate to "Appearance → Menus" in your WordPress admin panel, select the dashboard menu you've created and then add the "Favourites" menu item from the "Posterno" section.
For more info about the Posterno powered menu items, please refer to the documentation here https://docs.posterno.com/article/498-setting-up-menus.
Please note: the look of the favourites section or the entire dashboard page, may change depending on your theme.
