Sometimes users uninstall the app without deleting their account or profile. Those orphaned profiles remain registered to the school.
Use the administrator User Management tools to extract and remove such profiles, or to send guidance asking users to delete their accounts. The User Management function is available from the administrator menu.
This function removes all members from each group at once. After running it, all groups will have zero members.
Use this only when you will re-register group memberships for the new school year (for example, when you plan to have users register for new groups at the start of the year).
Be aware that many users who forget to register again might not receive initial messages in the new school year. Before sending group-targeted notices, verify group membership lists.
The bulk removal can be performed from the administrator User Management tools.
This operation resets all users' group memberships at once and can cause confusion. Prefer the step-by-step group update workflow above when possible.
