Mac OS X 10.11.6, SDC 2.21.04.71. Its certificate expired April 8 2018 so it won't connect securely. Check for Update... fails with an "Update Error", and it can no longer be found in the App Store, so I can't update it or re-download it. (The Mobile Communicator for iOS is still available, though.)
I've been relying on this. What gives?
