Why do I only see the sample report?

You'll see the sample report until there's a real report to show.

Group games: a report is saved only when the game reaches the end of its last round. If a game is ended early, no report is created.

Assignments: the report appears in Game reports as soon as you create the assignment and fills in as students play.

Check the filters: Game reports shows the class chosen under Filter by class. Games played without a class are listed under Games played without class.

Class progress shows a sample until students in the class have played while signed in during the last 14 days.
