In this PnP Webcast, we’re introducing the SharePoint “Modern” user interface experience scanner. Using this command line utility, you can scan your tenant for compatibility with the SharePoint Online "modern" user interface experience. The scanner will give you a detailed view of sites that are not using "modern" pages, lists and libraries that are rendered in "classic" mode and finally it will also give you a report of customizations which are simply ignored in the "modern" user interface.
