• Connected Apps: Some Apps (like Finance or Cabri Jr) are protected and may require a specific “Reset Apps” command.
• Variable Locking: Locked variables must be unlocked before they can be edited, though a full reset bypasses this.
• Grouped Data: If you have grouped variables, they are stored in the archive and require a deep clear to remove.
