When setting up an assignment I checked the 'allow moderation' box. I used Speedgrader to enter marks and comments. My students were unable to see my comments and the marks entered did not transfer to the Gradebook. I was able to enter the marks manually. It appears that the moderation aspect requires a moderator to enter marks and comments or to accept the original marks and comments before these are available to students. The guidance (https://community.canvaslms.com/docs/DOC-9978-4152477048) available and response received in case Canvas Case - 03048172 indicates this could be the case but implies a moderator's comments override the original comments, rather than saying this is essential. Is this correct? If so, then there needs to be a warning to this effect against the checkbox in the assignment setup page. If not, then I need another explanation of why my students could not see the comments and the marks did not transfer from Gradebook and would appreciate advice.
