Nested Team Leaderboard allows chat functionality with fellow team members. These messages appear in chat when team members join a challenge that includes team chat and will remain visible for 10 days after challenge ends.
Level 1 (Top Level): No chat functionality available — teams at this level cannot communicate with each other.
Level 2 — only members of the same sub-team can chat. The Admin Account Owner can disable/enable this setting in the Admin Center.
Navigate to App Settings in the Settings.
Now enable Nested Team Chat.
