In my own pc, with an older version of TV I don't see this issue. On newer versions, connecting to a PC with teamviewer host, and 3 monitors, the icons at the top for "toggle monitor" don't appear at the start. Clicking "view" - but not actually selecting anything is enough to make the monitor icons appear.
So please fix it so as before, it populates the full toolbar when doing a connection, as it is majorly inconvenient to have to select view before switching to the other monitors. We quite often need to switch to the second or third monitor, and the operators are frequently dipping in and out of the target machines.
