Co-op leaders and co-leaders can restrict other co-op members from participating in regattas. If a regatta is currently in progress, the player will be restricted from participating in the current regatta. Otherwise, they will be restricted from participation in the upcoming regatta.
To restrict a player from participating in a regatta, tap the player's name in the list of co-op members and choose Restrict from regatta in the pop-up window.
To take part in the next seasonal regatta, the player needs to check off the corresponding point in Settings. They can take part in the next interseasonal regatta regardless of their status.
