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.
Uncertain Long-Term Support
