Hello, I open this topic to report a bug that happened in all the games of this tournament.
In all these games, black was unable to submit their first move for at least 10 minutes.
In 2 of them, the opponent was able to see the first move, but when they clicked both the moves disappeared after showing a quick error ( example).
We have been able to finish the tournament but it has been very long.
I hope this will be an isolate case, but I prefer to report it
