I have a course that made use of groups and the new "Available for group members only" which meant that the first assignment (with enabled Turnitin) they created were only created for 82 of the students. It seems that only these students were synced to Turnitin. Now when a new assignment is created (enabling Turnitin). even if no grouping is used, only these students are added on the Turnitin list. So any other students who upload assignments get a 118 error message.
How can I sync the whole class list to Turnitin?
