  While the community is active, the quality of user-contributed solutions and explanations can vary significantly, and some may not follow best practices or be optimal.
• Platform Performance Issues
  Some users report occasional performance issues such as slow loading times or glitches during peak usage times, which can be frustrating during practice or contests.
