This is the first time I see this happen in the 4+ years that I’ve been playing this game. I see the “Matchmaking starts in…” countdown, then “Searching” and in less than a second it cancels the matchmaking and returns to “Find Match”. Don’t know if it’s relevant but it happened after I upgraded my Windows 10 to version 20H1. Anyone else experiencing the same?
