If you are part of a team and you would like to disable or enable the teams chat in game, tap on the Team section and you will see the ‘More’ option - this option only shows once you have joined a team.

If you tap on ‘More’ it will bring you to the team info section – in here you will see the option of either ‘Chat On’ or ‘Chat Off’. Tap on this to either disable chat or enable it.

Don’t panic about helping teammates with lives if you do disable the chat feature as you can still give lives to teammates and receive lives from your teammates even when you have the chat turned off.
