I am part of a multi-section course using Canvas. My Canvas settings are restricted to my three sections; I cannot see any other student sections. I created a group set and groups for three discussion boards using the instructions. According to the instructions, "Only members from this group will be able to see and contribute to this Discussion." However, all the students outside of my sections can see my discussion boards and receive notifications each time I open a new board.
Any ideas on what is happening and how to fix it?
