When this happens for files uploaded to Sheet, the file does non return correctly in the Canvas previewer because the browser interprets it equally another file type; consequently, users either see  a string of code in the previewer or do not see the magnifying-glass icon for previewing the file at all. Fortunately, this issues does non affect users' ability to download files, just the ability to preview them, so anyone with access to a file in a Canvas site can download it past clicking on the file link fifty-fifty when the file preview is not working.

Lost SpeedGrader Comments in Firefox

Nosotros have learned about a new Firefox issues affecting SpeedGrader. When a Teacher, TA, or Grader uses the margin commenting feature for annotations in SpeedGrader with Firefox, they must click exterior of the comment bubble on another area of the document in guild for the annotate to be saved. This has led to several cases where terminal comments are not being saved when the user navigates to the next student submission.

We recommend the following workaround for this issue:

  • Utilise a supported version of Google Chrome or Safari instead of Firefox.
  • If y'all must use Firefox with SpeedGrader, make sure to click out of the comment bubble onto some other area of the screen when adding your terminal comment on a newspaper to ensure that information technology is beingness saved before navigating to the next pupil submission.

Too, please note that if you leave SpeedGrader open for a submission for a long time, you can also lose comments, fifty-fifty when working in supported browsers. While it might seem that this behavior is the same equally the Firefox bug, please exist assured that it isn't. Rather, it is the intended beliefs of SpeedGrader when it has been open for a submission for an extended period of time.

If you intend to stay in-touch with students from a form after the term ends, we recommend asking if they would like to exchange email addresses.

Teachers and TAs in "Concluded" courses tin message one some other using the "Concluded" messaging pick.

No Email Notifications for Courses in Future Terms, Just Push button Notifications

When a gradebook is exported, the file is sorted alphabetically by concluding name, then a re-sort of the "Student" column afterwards some other cavalcade has been sorted does not restore the file to the original sorting order.
