Im having some trouble using the new sharing features in Finder, Preview, etc. Having tried with many different file types (pictures, text, audio, video), it only ever lists Messages and Airdrop. Not Email or Twitter. I have connected my Twitter, Facebook and Gmail accounts under the Mail, contacts & calendars section in system preferences, and set up Chrome (Gmail) as the default mail application in the Mail preferences. Have I missed something Im supposed to do to get it working? Im located in Norway atm, if that makes any difference.
