Therefore, the system cannot relay the Airplane mode settings to the devices. As the name implies, it’s especially useful when you’re on an airplane. This issue occurs because the Airplane mode setting changes before the wireless devices are configured.

In this scenario, if you turn off Airplane mode before the wireless devices are initialized, the devices stay off even though Airplane mode is off.
