Hello @Alex911
Thank you for contacting the Canvas Community. We're sorry to hear you've been experiencing issues with editing announcements. The guide states that:
- Editing an announcement will create a notification in the User Dashboard and Course Activity Stream. If you want users to receive the edited announcement via their notification settings, you will need to create a new announcement.
This should create a notification in the activity stream, but it won't render a new notification/email. You edited your announcement and then went into student view? Or you masqueraded as an actual student and confirmed it wasn't there? Not everything within student view is 100% represented as real students will see. Unless you are acting as a real student or logged in as one, it is likely that it won't display while a teacher is in student view.
