HI,
I was Screen Sharing from Message beta to someone the other day and I can normally end the chat by clicking their red Squares.
However this did not work and it took repeated attempts by the person themselves.
One issue may have been that his end was doing a Time Machine backup and the whole Screen Share was slow and jumpy.
CMD and ESC together are also supposed to end the Screen Share.
