I know a lot of people are saying this, including my friends, but don’t play competitive. Lots of my friends are other people on the forums are saying they aren’t gaining any SR from winning competitive games, and aren’t losing any SR either.
One of my friends said it was because it was right after an update and there are lots of bugs, so if I were you, I’d stay away from comp until a little bit after the update. (My friends said this usually happens around major updates, but this is the first time I’ve heard about it. I think he meant for when they add PvE gamemodes.)
I had a game glitch after round 1, everyone had to leave, then i lost 2 due to leavers, lost sr for those, won 1 and gained sr, won 3 more and gained no sr at all.
