Hi - I am a TA and I am using Canvas for the first time to have a weekly discussion thread for my sections. I have created separate groups for my three sections and specified which users have access to the groups. However, announcements posted to the group pages seem to be going to everyone in the class, and I can't see a way to control notifications. Does anyone know if there is a way to fine-tune the notification settings so that group notifications just go to the specific group? I really don't understand why this is happening.
