We have several discussions that are not behaving as expected. They are configured as group discussions and students were able to post and reply to posts by students from any of the groups. However, when the students went back to the discussion after the due date, the past discussion posts were hidden from them. The administrator and instructor can see all discussions, but students cannot even see posts from other students in their own group including replies to the main question and replies to students. I tried removing the Available Until date, but this did not change the visibility of the posts. I also disabled the Users must post before seeing replies option, but this also did not change anything. Can anyone shed some light on this? This does not seem like the intended behavior of the discussion.
