It sounds as though you are trying to view things over a mobile or data connection.
A "connected device" is something that is connected to your Home HSD network. IF you are connected to your network and there are still channels that are doing this then you may need to call for a service appointment.
Anything through the app should work when on your home internet, unless it was just brand new installed yesterday, then it may take a few days to work properly.
