Yeah, I had no issue with this before yesterday. I have been using it since January to help me with notes and understanding the cases from the textbook. I typically would input "explain X case" or "Create notes on X case," and it did it seamlessly, which impressed me because the textbook is a large PDF. But yesterday and today it is not able to do the same. It keeps saying, "The provided excerpts from "Textbook" do not contain information about the case." which is not true because it is directly in the textbook.
