I can't find the session file for the quiz I ran in TurningPoint Cloud.

The first thing to check is whether or not it is in the Auto folder. When you don't choose a participant list before you open polling then TurningPoint automatically files it there.  Sometimes you'll have to scroll to the left to see that there is a triangle next to Auto or the participant list.  This means that it can be expanded to see the session files associated with it.

If the session file is under Auto then you can click and hold the mouse button down on the session file name and then drag it to the correct participant list and let go of the mouse button.  This automatically reassociates all of the device ids with the correct participant.

If the session file isn't listed under Auto then it might be in the backup sessions folder.  To see if that's the case first open the TurningPoint software folder.

If you find the file there then you will need to import it so that you can see it listed on your Manage tab.
