openthread.thread.home.arpa in network. Don't have Google Nest/HomePods/HomeApp. Thread item has removed left navigation in Finder.
I've seen the other thread about this, and it looks like it could be a neighbor's device. That's fine, but it is monopolizing my view of Finder. The left hand folder view won't show expanded folders. How can I restore that so I don't have to keep clicking icons on the right window?
