This just happened to me too.
1st: My opponent didn't show up for the game in round 2 and the point got split, instead of assigning me the win
2nd: When round 3 started I was issues a bye telling me that I was "detected offline" even though I was most definitely online following the other games of round 2
I'll wait to see if I get to play in round 4 or if I am still "detected offline"
Just playing first tournament on chess.com.
I've lost a first game, went to settings to adjust some board/pieces/sound things and then got a message I got a bye because the system detected I was offline. I was online all the time though.
Is it a bug or do you need to have tournament focused all the time or otherwise "system detects you are offline"? Now I am afraid to even open my game history cause that may mean another bye.
Did I run into some bug or is the intention that I can't do anything on chess.com between tournament games?
