Same here. Recently I had reported this and gave all information I could think of to @jdcannon
Though, that was a few days ago and it seemed to have been working for a bit, I do not know the status at the moment as I have not noticed any of my games not triggering the conditional moves. Many, since the report, simply did not trigger because the opponent did not make the anticipated move.
I have yet to catch more games where the conditional moves have not triggered as expected.
Edit: Looking at my messages for the dates, this was just over a week ago.
in two games recently I created conditional moves that did not trigger. Conditional moves have worked for me before.
