@abhijith_telstra In Cosmos React UI, the current behavior of resetting to the default tab when navigating back to a parent case is due to the page not retaining its state after navigation. To avoid this, you can use the "temporary work object" pattern or configure the navigation settings using usePageState or localStorage/sessionStorage to remember the active tab index. Store the selected tab information before navigating away, and when returning to the parent case, read that value and programmatically activate the same tab. Additionally, check if the latest version of Cosmos UI offers enhanced state preservation features or use the Page State Persistence configuration if available in your version. This helps maintain a smoother user experience without resetting views
