On iPhone, Dropbox no longer shows an Export file option for me in the
Files tab for [FILENAME] or [FILENAME] files. The only visible Share
option pushes link sharing, and the only way I found to send the actual
file is a clumsy workaround through Print and then the iOS Share button.
If this is an intentional product change, it makes Dropbox much less
usable for sending files directly and pushes link sharing in situations
where recipients often cannot use links. Please bring back a direct file
export option in the iPhone app. Otherwise, I have to look for different options for cloud storage. Many people I send files to cannot access the links.
