I don't think it's a bug. daily tournaments require tiebreaks for each group in a round and Swiss don't so I don't believe any were ever included there.
The site added a number of additional tiebreaks to live events, all of which should be easily calculated based on the rounds,
so I was testing the swisstournament endpoint, and I was unable to receive the tiebreaks for players
I am trying for
https://api.chess.com/pub/tournament/1st-sat-rapid-2024-12-1700-4560201/4/1
actual tournament here:
https://www.chess.com/tournament/live/1st-sat-rapid-2024-12-1700-4560201
in the docs it mentions getting the tie breaks for daily chess tournaments is possible
https://www.chess.com/news/view/published-data-api#pubapi-endpoint-tournament-round-group
but why the tie breaks are not shown in the normal Swiss tournament? I think this is a bug, which should be fixed.
Thanks!
