The "Getting started" card disappeared, how do I bring it back?

It does not come back: the card leaves Today as soon as the four essential tasks are done, and for good after the congratulation message. There is nothing to reopen.

If it disappeared before everything was done, check that you are the owner: instructors never see it. Otherwise, reopen the app or come back to Today: it reappears as long as the four tasks are not all ticked.

To review or change what you created, go through the screens themselves: Students, Schedule, Attendance, Subscription types and Settings.
