I've been trying to upload a large number of photos from my phone to Dropbox in batches of 12. Sometimes it goes fine, sometimes only 9-11 of them upload, sometimes one or two random other ones from the same folder get transferred as well. And now I can't open the Dropbox folder at all. I'm baffled that such basic functionality is so faulty and unreliable, I'd be better off just buying an external hard drive for backup.
