Your SharePoint modern communication and team sites will soon feature the SharePoint app bar which provides quick access to customizable global navigation as well as other intranet resources. The SharePoint app bar makes important content and resources easily accessible for users on these sites, regardless of where they might be in SharePoint.
Roll out to Standard tenants will begin in early May and complete by the end of May.
Roll-out: tenant and user level
Action: review and assess
How this affects your organization
Users access the SharePoint app bar from the upper left-hand side of the browser on the SharePoint start page and throughout modern SharePoint sites. The SharePoint app bar improves global wayfinding and dynamically displays personalized content for sites, news, and files.
If you take no action, the new SharePoint app bar will appear on your SharePoint modern communication and team sites. Until you customize it, the global nav entry point will refer your users to their SharePoint start page.
