  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.
• Uncertain Long-Term Support
  As a smaller company, there might be concerns regarding the long-term viability, updates, and continued support of the service compared to more established providers.
