When I play, all my opponents show as “Your Opponent”. I mean all. Even when I play against friends. I know there is a privacy setting to appear offline that people can use, but I think there is a bug because I get this for everyone. Even battling friends. All games on the ladder. I am playing using Mac.
You can toggle Streamer Mode by using Ctrl+Shift+S or Cmd+Shift+S on Macs.
You can tell that Steamer Mode is active if your name appears as “You” instead of your name.
This will take effect when you start your next match.
