When you play standard unranked 2v2, you are allowed to chat with your teammate (team chat) and your opponents (global chat).
I found one particular issue of the in-game chat quite annoying: Before a match starts, you can talk with your teammates. As soon as you find a match, however, the chat gets reset and the stuff you were about to write and have been writing so far is gone.
It makes sense that there is a new global chat whenever a new match starts - but for the team chat it does not entirely make sense to me.
Maybe a solution would be to separate the team chat and global chat “streams” so the team chat persists and the global chat gets reset?
