I have 5 sections of science and they are all cross linked on Canvas. In Announcements I wanted to send my students a specific link for each class period, so In the "post to" section I chose a specific class with the specific link. However, when I check on student view, it shows that a student can see all announcements I made to each section. How can I change it so the announcement goes to the specific section I designated it to. I attached an image of student view.
