My sonos sub is connected to a sonos amp (and two speakers) in my lounge. I have been trying unsuccessfully to relocate the sub to the TV room and add it to the beam and TV setup.
When I try “remove sub” from the amp, as well as reboot/reset and swtiched off the sub, it still somehow remains as an “unassigned sub” on the app (I would think it should disappear from the app altogether so that you could reconnect to a new room as if it were a new sub). When I then try and assign it to the TV room I get the error “there was a problem adding your sub. Check the network..”
There don’t seem to be any settings option to get around this dead end. I am able to assign it back to the amp.
the odd thing is I have done this before a few times successfully on the old app, so I am not sure if the bug is on the new app, or on perhaps a beam upgrade which makes it unable to see the sub?
