I am encountering a frustrating bug in Google AI Studio.
Until the recent update to version 3.0, I was always able to simply drag and drop PDF files into the prompt window without any issues. Since the update, this feature seems broken: when I drag a PDF into the window, the file just disappears and doesn't get attached.
Just to be clear: the size of the files has not changed since then.
Strangely enough, uploading screenshots works perfectly fine without any issues, so the upload function isn't completely broken, it just fails with PDFs.
