  • Limited Advanced Features
    It may not offer the same breadth of advanced productivity and collaboration tools that come bundled with larger platforms like Microsoft 365 or Google Workspace.
  • Smaller User Community
    Due to a smaller user base, there may be fewer community resources, third-party tutorials, or troubleshooting forums available online.
