I was in a 3 man group in Overwatch, 2 of use “joined” a competitive game, but never actually entered the game and then were suspended as leavers and lost SR in all three roles, not just the one we were queued for. The popup for game found showed but we never entered the game and never opted to leave. The third person which was the group leader, at the same time joined a quick play match and did not receive a suspension or SR loss.
