When I go to the Team Page and click Scoreboard there is no option to + Add a Score and/or Highlight.
The Game has to have already occurred. For example if it is 7:00 pm and you have a 7:30 pm game, you will not be able to enter the Score and/or Highlights until after the start time of the game. If its 9:00 pm and you had a 7:30 pm Game, you now will be able to enter the Score and/or Highlights. To enter Scores and/or Highlights see How to add scores & highlights for athletics teams.
