The event now lasts for 24 hours so players can find a time that work for them to play, whatever their timezone.
Also, you can create and choose directly your team in the list. It’ll be easier and will prevent players from not being able to join at the last moment if I’m not available to assign them to their team.
Before joining a team, please make sure the players are ok that you join their team. In case of abuse, you will be kicked out of the event.
