A change that has been released on Saturday may have impacted some schools if they do not have any students in their file or have not allocated any students to classes, which will cause all classes to be cancelled. The solution is to add students to classes in Edval timetable file so that at least one class per day has students allocated and sync the file (in particular Class-list data) to Edval Daily. We will address this issue to ensure that Daily works for schools without students asap.
