I have a problem with opening PDF files in Adobe Reader on my Android device(Nexus 5 with Marshmallow). After clicking on link with PDF I used to see file being downloaded and then opened in Adobe Reader app. Now I'm only prompted with an error message that states: The file could not be downloaded. Please save the file to your local storage and then try to open it.
Have you experienced similar issue? Have you any idea what may cause such probem?
There could be issue with authentication from the URL from where you are downloading the PDF. A workaround to this is open the PDF through Chrome and then save it in your local storage and try to open the saved PDF through Adobe Reader.

I also tried to save documents to Adobe but it says save documents to local storage and when I download with chrome they don't show
