Adobe keeps prompting to save file, when it has already been saved

Report · Sep 28, 2016

I am creating a pdf from Office and saving it into a SharePoint site. This all works fine and the pdf file opens in Adobe Acrobat or Reader. I can then add in Document Properties as necessary and then check in the file through the SharePoint /Office365 option under File Menu. All Good. I then go to close the file, either through exiting Adobe or using File, Close, and I get a message saying do I want to save the pdf file? Very annoying. If I click Yes, I go round in a loop because the file is already saved, if I click No, then it closes the file. How can I get to close the file, which is now already in SharePoint and checked in, without being prompt to close it again.
