The deprecation of the Legacy Navigation Bar is a terrible user experience decision. Being able to view the breadcrumbs at the top of the screen (or at all for that matter) is extremely useful for both business users as well as for IT administrators. For IT administrators like myself, when sending or receiving screenshots of D365 screens, it is extremely helpful and necessary to see the breadcrumbs in order to know how to navigate to that screen. For business users, the same applies when internally training new users in D365. The "restyled navigation bar" doesn't add any new feature (and only removes a feature) as the Search function is already available in the top right corner on the Legacy Navigation Bar. Please seriously reconsider the deprecation of the breadcrumbs or at least find a way to add it back to the new navigation bar.
