Why cant I view the attachment in my Galaxy Note5?

[AC Question]

Till a week before I could view the attachments but now when I try to view the attachment it says "cannot find application to open the file". and its happening for all types of attachments, .pdf, .xls etc. I already have adobe pdf, and mobile office installed and it was working fine till some time ago.
