If the network sharing is set to ‘Not shared’ it is only stored in the current device. To be able to share the network choose one of the other sharing options. Then the network is saved to the Casambi cloud service and it can be shared with other devices. To be able to use shared networks all your mobile devices need to have connection to the internet.
