Hi @JaimeLongo ,
I tried using the Student View to annotate a document, download that annotated document, and then upload it as a new assignment, I was able to see highlighting and box frames, but in order to see text boxes and comments, I had to hover over the document (and there was no mark to indicate a comment - I knew where I had put the text boxes and comments and found them by moving my mouse around).
I was disappointed that this method didn't work, and I'm hoping someone else may have a better suggestion. This annotation tool is relatively new, and maybe this suggestion could be posted on the Canvas Idea board.
