A faculty member I support updated a template the department placed in the Canvas Commons. This change overwrote her current course content. When prompted to update there was no warning that material would be overwritten or lost. If a warning about what is going to change or be overwritten can be more prominent this would be helpful for instructors. The instructor lost 2 semesters of work and updates because of the template update. If materials already exist to help Canvas users know more about what will change from an update to Commons resources please share. Thank you.
