McGraw-Hill Connect assignments that require manual grading will automatically display in the student’s grade book as a 0 until it is graded. Once the assignment has been graded in Connect, the students grade will update in Canvas Grades to the correct score. McGraw-Hill is aware of this issue and has not provided an ETA on when it will be fixed.
Work Around: This problem only affects MH Connect assignments that are set to auto sync with Canvas. Disable the auto sync feature for any assignments that require manually grading, and once all submissions and grading are completed in MH Connect then enable the auto sync to transfer the grades to Canvas.
