Canvas Section Not Showing in Navigation
@revouprojects This sounds like maybe something custom your institution may have created. I can't think of any "Section" areas that shows in a navigation bar that is native to Canvas. If you go to your course "Settings", there is a section tab that you can use to create new sections. Then in the "People" area of a course, once you click the "+ People" button, there is a drop down of all the sections so you can enroll the student(s) in that section. Beyond that, I am not aware of any section areas in the user interface.
Maybe if you have a screenshot of where it normally would show for you, we could verify if it is something custom or what exactly is going on.
Hope this helps!
