Can't Attach Filesin Dropbox to Messages

[Kagemi]

I'm not sure if this is a Samsung or Android problem/
Using the standard messaging app on Galaxy S5 I used to be able to attach files in Dropbox to messages. Now Dropbox doesn't appear in the list of available sources. How do I restore this and why did it disappear?

Try re-installing Dropbox. I am using the current version and have no problem attaching files there to my AT&T Messages app.
