content: It seems that Adobe is obsessed with bringing the users to their cloud by creating deliberately problems to any other mode of operation. I used to be a heavy user of Acrobat on Galaxy tab S3 for editing PDF files. Now its a complete waste of time. Big files wont open and if they open changes will be lost giving the notorious spurious message for read only files Clunky menus everywhere if you dont want their cloud. Uninstall it. There are much better apps out there.
