What's New

✨ ICS Calendar Feed

Subscribe to your learning schedule in any calendar app:

• URL: https://your-nextcloud.example/apps/learning/api/leitner/schedule.ics
• Shows all pools with due cards for the next 30 days
• Overdue cards appear as today's events

🐛 Bug Fixes

• Dashboard student count: Fixed double-counting of students enrolled in multiple courses — now shows unique student count
• Notification icons: Fixed missing icons in Nextcloud mobile and desktop clients
• API stability: leitner/stats and leitner/due now return a clean 400 error instead of HTTP 500 when called without poolId
