When using PDF Spaces and AI Assistant, the AI Assistant doesn't always recognise files that have been added later in the process. So, for example, if you are completing a research paper and some new evidence has come to light, you add that new evidence, and use AI Assistant to search all papers, there have been times where it will not reference that new paper. This risks leading to gaps in research for people who may be working with files closer to the 100 file limit.
