Cannot upload assignment feedback via Grade Center’s “Work Offline” mode

Problem: Downloading an assignment in the grade center, then entering feedback into the feedback column in Excel, then uploading the file to the Grade Center, does not result in the feedback being saved.

Solution: This is a known bug, and a fix is expected (though not garaunteed) sometime in mid-December. In the meantime, feedback can be entered via the web interface on a supported browser.
