By default, a bridge is set to your account business unit and is not assigned to a location. If your account structure uses business units or locations to control user access, assign a bridge to a business unit or location to ensure users have access to the devices they are responsible for.
Go to Devices > Bridges.
Select the Name link of the bridge.
Select Show Advanced Options.
Set the assigned Business Unit or Location.
From the Business Unit drop-down list, select a Business Unit.
(Optional) From the Location drop-down list, select a Location.
