We use Infinite Campus as our SIS. When the marking period switches to marking period 2, our teachers lose the ability to use the Copy To.. feature to copy materials between their active courses. Canvas "sees" the courses coming from IC as separate entities (one for each marking period) and thinks the other courses are no longer "active". I realize that cross-listing helps with this, but for teachers looking to copy more generic materials between courses, they are left with Import as the only option.
Would love to see this work better for our teachers in the future.
