I'm receiving a lot of contacts from students who report that they submitted an assignment via the Turnitin LTI but their submission no longer shows up in Canvas. I see them submitting the assignment and visiting the /submissions page, presumably to check their submission. This isn't terribly unusual during the semester-start (missing submission contacts) but it is unusual to see so many coming from one tool. Given that we're only able to look at it after the fact (because the students don't notice until later that it isn't there) I haven't been able to do much troubleshooting.
Anyone else out there seeing similar issues?
