When loading the game, the chat panel will show on the right.
If this isn't showing, then you may need to check if you have Chat turned on.
1. To check this click the three dots in the top right-hand corner of the game itself.
2. This will open a menu and click 'Chat' at the very bottom.
3. If the chat facility is turned off the speech bubble will have an X inside it and the panel will not show.
4. If it's turned on then you will see two horizontal lines.
