ICON - Gradescope is providing an error when clicking "Post Grades to ICON" for linked-assignments. An error message states an assignment must first be linked, when already linked.

Until this issue is resolved, grades can be exported via the 'Download Grades' button on the 'Review Grades' page of the assignment, and then uploaded to Canvas' Gradebook:

1. Export exam grades from Gradescope as a CSV file.
2. Edit the CSV file to match the format for importing the exam grades to the Canvas Gradebook. *You can obtain a file with the correct formatting by exporting the Gradebook. 
3. Import the grades into the Canvas Gradebook.

Gradescope developers are working on a fix.
