After you've generated a grade's fixture and viewed the grade's regular-season fixture, you can now view your finals fixture provided you've enabled 'finals' during your fixture generation setup.
To explore further, select the Competition Management main menu item, and then the appropriate Competition and Season tile, and then select the Grades tab, and finally the 'Finals' sub tab.
The finals round format is determined by the finals options you chose when generating the finals fixture with placeholders for the team names. As teams progress into the finals, these team name placeholders will be replaced with specific team names after you assign finals teams.
Similar to the regular season's fixture, you can edit the Game Details (time, venue, and court) and Update Scores & Stats using the '3 dot ellipses' icon located in line with the appropriate game details.
The 'Add a game' button allows you to add a finals game to your finals fixture. Learn how to do this in the Adding a finals game to a grade's fixture article.
