Pages for iPhone open in another app
Some months ago Pages began crashing whenever I set up iCloud - so I decided to save files in Dropbox. I do this by using the 'open in another app' feature - w which worked until today. Now when I open Dropbox to save a file I created in pages it does take me to the Dropbox app but will not allow me to save it there.
iPhone 5, iOS 8.4.1, OS X 10.10.5
