In the group "Everyone" nobody is set as admin by default. This means that the following is also displayed for the school's SDUI admin in the "All" chat group.
The background here is that we consider it unlikely that a conversation should be opened with the entire school.
This is also related to the fact that the list of members of the "All" group cannot be viewed. Only the group admin can see the member list.
This is independent of the attitude towards the Sdui-Admin / Sdui contact person.
In order to still be set as the admin of the group "All", the SDUI admin can contact the personal contact of SDUI. We can do this for you.
NOTE: The "All" group would be needed for an announcement (such as school closure, general announcements) for which at most a read receipt would be desired. This would be done accordingly via a news post. In the linked article "How do I write news in the start area?" you will find instructions for creating a news article.
