Let's play! - During a game

I can see the video/audio file on the team’s answer, but I can’t get the file open. It looks like it’s still loading.

The team has sent their answer before the media file had completed uploading the file to the answer field. You can return the exercise to the team and instruct them to wait until they can see their answer on the screen before they send their answer.

I returned an exercise to a team by mistake. Is there any way to unreturn the exercise?
