Worked on the jellyfin.org repository to enhance user-facing documentation related to Active Devices playback issues. Developed a comprehensive Troubleshooting Guide that addresses scenarios where playback progress is not displayed, focusing on system clock synchronization and NTP enablement for systemd-based Linux environments. Utilized Markdown to structure clear, actionable steps, ensuring users can independently resolve common playback problems. Collaborated with both documentation and engineering teams to ensure technical accuracy and traceability, linking updates directly to relevant commits and issues. This work improved the effectiveness of user support by reducing time-to-resolution and empowering users with detailed, self-service troubleshooting resources in the documentation.
