The purpose of a warm-up week is to help players ensure that their trackers are syncing as expected while also providing the opportunity to become more familiar with the requirements before the game is in full-swing.
Any player who does not meet the game requirements during the warm-up week will not be disqualified but all players are encouraged to use this time to explore the game and app experience.
If you joined a game during the warm-up week, the warm-up week begins the date the game started, not the date you joined.
Note: Not all games have a warm-up week so be sure to review the game details to confirm if that specific game has a warm-up week.
