|I am confused with this either. In the past, I have had queeries and asked them but never received a reply, so I have given up. All I can say from my experience is that you can add one move and it should show. Like you, I had added notes in brackets but could not proceed with the rest of the game. I then put thhe notes outside brackets and in [..] and left the moves in brackets and could continue with the rest of the game. One thing bugs me and that is the annotated games appear OK in public but in my own games, I can only play the game until the start of the annotation!!
Do you experience the same problem?
