Hi Ian,
  it seems that you already have a br0 bridge device created outside
NetworkManager.
This would end up having br0 "unmanaged" in the NetworkManager device
list: so when you create a connection for br0, NetworkManager will not
be able to attach it to br0, as it does not manage it.

You can either avoid creating br0 outside NetworkManager or do a:
"nmcli device set br0 managed true" to allow NetworkManager activate the
connection on br0.
