I have this issue as well. I have tried to spectate pro games while pros are playing, and so far probably 1 out of 10 games have been listed for me. I know they are playing because they are streaming and have the twitch chat on stream in real time.
This pretty much kills small casters. Please fix it.
It’s still not fixed. You can only get into a game before 10 or 15 mins. You can’t see the game that is being played for more than 15 minutes unless you enter the game before 15 mins.
