I'm a new user--my college just switched to Canvas from Blackboard spring 2018--so forgive me if this issue has been addressed in a previous New Idea.
In short, here's the problem I've found: while using the Highlight Annotation to comment on student papers, I'm finding that I cannot drag the highlighter across a page break. If a student has a wonky sentence that starts at the bottom of page 2 and continues on page 3, I cannot highlight the full sentence and post one comment: I would have to highlight the portions separately and make two comment boxes.
Maybe there's some trick I've missed, but I suspect it has to do with how Canvas formats uploaded documents. Has anyone else experienced this issue? Is anyone at Canvas working on a fix?
