Reproduce the problem from the Apps > Discover tab using the Search icon, then follow the Unified Search and Search Everywhere entry points to see why uninstalled apps produce no results. Confirm the intended behavior with maintainers, then add a regression check showing that app search handles uninstalled apps or that navigation reaches the appropriate app list.
