Explanation
In Adobe Commerce, the visibility of a widget is controlled by its layout update settings, which explicitly define the store views where it should appear. When a new store view is added, existing widgets are not automatically assigned to it. To resolve the issue, the widget instance must be edited. In the "Layout Updates" section of the widget configuration, the new Spanish store view must be added to the "Store Views" multi-select field. This action instructs the system to render the widget on the specified pages within the new store view.
Why Incorrect Options are Wrong
A. Duplicate the CMS Block and append en-ES to the block id.
This is incorrect. Store view visibility is managed through specific assignments in the admin panel, not by following a naming convention for the block identifier.
B. Update the CMS Block and select the language from the Locate multi-select.
While the CMS block must be assigned to the store view to be displayed, the primary reason a widget does not appear is that the widget instance itself is not configured for that store view.
D. Duplicate the Widget and delete the original as Store Views can only be selected when creating or duplicating widgets.
This is factually incorrect. The store view assignments for any existing widget can be modified at any time through the widget's edit page.

1. Adobe Commerce User Guide, "Widgets": In the section on creating and configuring widgets, the documentation specifies the "Layout Updates" section for controlling placement. It states, "In the Store Views field, select the store view where you want the widget to be visible." This confirms that the widget's own configuration directly controls its appearance on different store views.

2. Adobe Commerce User Guide, "Blocks": This documentation details the configuration of CMS Blocks, including the "Store View" setting. It shows that a block's availability can be limited to specific store views. This supports the reasoning for why option B is a potential but secondary issue compared to the widget's own configuration.
