When launching an app through Meta Quest Developer Hub (MQDH) via Link, controllers do not automatically connect or render in the app until a user physically presses a button on the controllers. This issue is specific to the app launch flow initiated from MQDH through Link, suggesting a problem with controller initialization or wake state. Hand tracking and controller representation are not visible until user interaction occurs, although the underlying connection is eventually established after a button press, allowing controllers to function correctly.
