This is the information that displays to students on the Discussions page for a graded discussion on which the instructor has set a due date and an available until date:
Could you elaborate on the details of the request?
I'm curious where you get this screen at. Below are two screenshots of what students see; one is for assignment (with available until) and the other a discussion without it.
Assignment
BTW, before I posted this, I opened a case in Canvas and it was confirmed that the available until doesn't show up on Discussions page - Chat Transcript: Case # 07531467
@adrianmd I took the screenshot from a student's Discussion page, and just reconfirmed that the available date is still there. Your screenshot is displaying the discussion after the student clicks in to the discussion from the list.
The section you mention is not visible to students so there is no way for them to actually see it unless they know the direct link to get there (or there is a way to make it visible).
@adrianmd Thanks for clarifying that. As you state, if an instructor hides the Discussions link from the course navigation (which, by the way, is something I used to do in my own courses), they won't be able to see the "Available until" information. We'll move this idea forward for further discussion.
