A code bug introduced in a recent change broke the rendering of double-grouped views in SharePoint Online, causing document libraries and list views using both Primary and Secondary grouping to display incomplete or no results. The issue began July 9, 2026, lasted approximately 76.5 hours, and affected some users' ability to view expected content in grouped document libraries and lists. Microsoft developed and deployed a fix, reaching over 99% infrastructure saturation by July 15, 2026, restoring functionality for the majority of impacted users.
