Upon canceling a search you can lose 50sr and get a suspension for no reason
It’s been long around but it’s going to be patched out soon
This happened to me the other day! First time it happened. Was in a group of 3 and the leader cancelled the search as soon as a game was found. I lost 50 SR which was really annoying as I was at my all time peak in SR 
Hey everyone. This has been a glitch I have been personally observing since the start of season 17. Basically the theory is that you were paired into a match at the same time you clicked cancel and this is happening often to many players because matchmaking has dramatically changed to have really fast queue times. The game client tried to exit out while the server marked you as absent. Until any news of this is addressed by Blizzard, be sure to only queue for a Competitive game if you are absolutely ready to play.
