TV not showing all devices attached to Smart Things

My TV on set up connected to Samsung Smart Things and when I opened the app on the TV it showed all the devices linked to smart things hub in my house. I have logged onto it tonight to see why it wasn’t notifying me when the ring doorbell went off, now it only shows those devices under “living room” and not the whole house devices. I have selected all devices at the top but nothing is happening. Can anyone advise if I’m doing something wrong? All I’ve done lately is attached it to a google home for the nest thermostat.
