The problem is that Canvas New Quizzes currently doesn't allow to be graded in concluded courses. This Canvas New Quiz Guide (https://community.canvaslms.com/t5/Instructor-Guide/How-do-I-grade-a-quiz-in-New-Quizzes/ta-p/1068) mentions this. The issue is that online courses may have the final week's content due on the final day of the course. Thus, the course ends on the final day, however, instructors still need to grade everything from the final week. This poses an issue with New Quizzes that are using essay questions or short answer questions.
The solution would be to enhance Speedgrader to allow New Quizzes to be able to be graded in concluded courses. In addition, this would reduce the stress faced by instructors as they would have to resort to manual grading in the gradebook to get around this New Quiz limitation.
