I just came to the forums to say I am having this problem. I also have a little further weird information:
I just completed a five-game tournament, in which I chatted in every game (“gg” at the end, at least), and received this message in all five games. More importantly, in four (I think — maybe three) of those games, my opponent who was “not available for chat” chatted to me. And in three (I think — maybe two), my opponent chatted to me before I chatted to them.
Hello, all.
I seem to be getting a huge number of players in succession for whom "chat is unavailable." I checked my settings, and I'm chattable. I haven't received any warnings regarding abuse or unacceptable language. Is anyone else encountering this problem?
TIA.
