It is advised that instructors who use Turnitin to confirm all assignment settings after conducting a course content copy.

A recent platform update to Turnitin has caused some Turnitin assignments to become unresponsive when attempting to access grading functions. We are actively working with Turnitin Technical Support to resolve the issue.
