We are working on some behind-the-scenes changes to Blackboard’s course settings in an effort to provide a better user experience. Moving forward, courses will not have default course availability dates associated with their term. This means that courses will not become available/unavailable on a preset date unless manually set by the instructor or department.
If you need courses to become available/unavailable on a certain date, view the Course Properties section of this article in our knowledge base: How do I set course availability in Blackboard?
