WHY WON'T PDF'S DELETE WHEN MOVED TO A CATEGORY
I have an IPAD Mini; software: IOS 8.4
In IBooks, when I move a PDF into a category (ex: knitting, quilting, etc.) the PDF use to disappear (from the PDF category). It no longer disappears, it remains in the PDF category. Having duplicate PDF's uses up memory, as well! If I delete the PDF in the PDF category, the file is deleted in both categories.
Thanks in advance for any comments.
