Resetting task status

Is there a way to move the task back if the transcriber hadn’t finished transcribing the whole thing and clicked Submit (passed it onto Review) by mistake?

Yes, the admin user can click on the project icon which brings up the project settings screen.

You can put it back to “start” and it will be available for further transcription.
