For quite a while, we have accommodated students with "Incomplete" in a class by adding a new section within the class, adding the student to that section, and setting the section to have an extended end date that is past the default course/term end date.
Up until recently, that worked fine, allowing instructors to put new due/availability dates on quizzes and assignments for those students based on the "Incomplete" section end date rather than the course end date.
We've just discovered, though, that now students in those sections can no longer take quizzes if the course end date is passed, even if the section end date is not. These students now get a "The quiz is not available because the course is concluded" message.
Has anyone else found this behavior? I suspect it's a change from a recent update, we don't know which one...
Was the new section added Before the course ended? And did the section have both Start and End dates entered? I've found that sometimes if one date is entered, but not the other, sometimes a setting doesn't work quite right.
It's possible you may need to submit this to Canvas as a ticket...
