Can't add local google TV to room in home

[LarsErikOsterud]

I have two Google TVs that are logged into my Google account and show up as local devices in Home.

But when I try to add them to a room it fails. After a long time "Logon to Chromecast" it ends with "Could not connect".

Have tried to logout and log back in on the Google TVs.

I have a third Google TV that is assigns to a room, and 4 cameras.

So why won't the last two Google TVs work.

I can control them from Home, but can't add them to a room.
