• Potential for Inaccurate Data
  Despite efforts to provide accurate information, there is always the risk of outdated or incorrect contact data being present in the database.

• Lack of Detailed Explanations
  The platform may not provide detailed explanations or learning materials for commands, requiring users to look elsewhere for thorough understanding.
• Potential for Frustration
