I am new here and am not sure if I should be starting a new thread - so please forgive if I should not have. I cannot do anything with a pdf which I have downloaded or otherwise received in Safari. If the pdf is open, for example, and I want to save it to iBooks, absolutely nothing happens when I hit "share". my list of options doesn't open and I am unable to send the pdf to any app or to printer, etc. I am running IOS 11.4.1, but this also happened with my previous IOS version. I REALLY need this function and have no idea what to do. Would very much appreciate any and all suggestions!
