Is this a question about the Acrobat Reader desktop app on a Windows/Mac computer?
What is the version of the operating system?
No not for desktop or mac. Its my samsung galaxy s6 phone. I have got the adobe acrobat app but its not letting me open or see attachments that come as part of an email. On my s4 it worked perfectly.
Are you unable to see the downloaded attachments in the "My Documents" section? Did you try using the floating action button to navigate to the attachment (see this - https://www.youtube.com/watch?v=fTrTPR9LEq8 )? Are the documents not listed in the "Local" tab?
