I seem to be having a strange bug where I and all my staff are getting system notifications or notifications of messages that we are not included in. This could be system messages to users or private messages from one user to another! not sure why we are getting these additional notification but this seems to be and issue after the latest update (I hadn’t updated since about 2 weeks prior).
Another instance of when this is an issue is I have enabled notifications for all users when an announcement goes out under the announcement category. Just now an announcement went out and I seemed to get a notification for every single user this notification was sent too!! (The list is way longer than the screenshot below).
