I was alerted today that we have a minor bug in the share you Empressr, function, while we work on fixing it here is a bit of a workaround.
-Make sure that you save and
publish the presentation, it should not matter if you choose public or private
-Close the Empressr creator/editor and go to your listing of presentations
-Click on the presentation to launch it, once loaded click the share icon in the bottom bar , it’s the envelope.
That should give you all the sharing options
