Review the EMM configuration to confirm phone hub has been disabled. On the EMM console: 1. Open "Set user restrictions". 2. Verify "Nearby notification streaming policy" is set to "NEARBY_STREAMING_DISABLED". If on EMM console the "Nearby Streaming Policy" is not set to "NEARBY_STREAMING_DISABLED", this is a finding. Note: From a Chromebook, if a device is connected to the Phone Hub, try to set up the Notifications and it will fail to connect to the device to complete the set up if phone hub has been disabled on the DOD Android device.
