The post addresses a subtle UX gap: deep linking can navigate correctly but still leave Shell tab selection visually wrong.

Fast path

• Prereqs: A MAUI Shell app with notification-triggered navigation
• Steps: Name your tab items, add a shell switching method, and invoke it on the main thread before navigation
• Result: Correct view navigation and correct active tab highlighting
• Next: Reuse the pattern for other deep-link entry points

What you’ll learn

• How to coordinate navigation and Shell state updates
• Why main-thread invocation matters for smooth UI behavior
• Where to place this logic for reuse across platform entry paths
