Is the course perhaps set to separate groups? Is it isolated to this one course?
Hi Emma,
Yes, the course is set up in separate groups. I'm at a loss as to why this error message would pop up in that context, do you have any other information to share about this? Thanks!
I would check permissions on the teacher role - if they do not have the permission to see all groups and are not in a group with the students, this might be causing this...
