I have a teacher with 3 published courses. She worked on the courses for several weeks. She was in the courses last week. Now, she cannot even log into Canvas. As an administrator, when I search for her as a user, she she is now missing as a user, has no access to Canvas, and the students in her classes are no longer attached to courses. When I look at her courses in our list of courses, she is the only person who has 0 students for her courses and 0 teacher. This is an import from Powerschool each night but her classes have not updated.
