Hi, I've got a new ipad mini and I've noticed that the 'open in dropbox' option isn't working. When I choose dropbox from the list of apps, nothing happens. I've tried different file types, and different dropbox apps, but nothing happens. Eg, if I have a PDF in Safari and choose 'open in dropbox', nothing happens. I've left it several minutes to be sure. If I select 'open in goodreader', goodreader starts and the PDF loads. If I then choose, from goodreader, 'open in dropbox', nothing happens. I've tried restarting the ipad (by holding the two buttons down until the apple logo appears), and I've tried resetting the settings. I've also uninstalled dropbox, restarted the ipad, and reinstalled. Any ideas, please?
