Fix daily notification [2 h]

この issue には説明がありません。

The issue title mentions fixing a daily notification but provides no details. Look for notification-related code, likely in a Django app or a scheduled task (e.g., using Celery or cron). Search for 'notification' in the codebase and check any existing tests. Determine what the bug is and what 'fixed' looks like by examining the notification logic and any related logs or comments.
