You see Home, but it doesn’t exist
WHY BREADCRUMBS ARE NOT ENOUGH
If we use, for example, only the breadcrumbs, we can seem inconsistent. In the breadcrumb string in fact, it’s visible a navigation level that it’s not explicitated in the information architecture (home level). This could get the user confused.
