Problem for add friends


Problem for add friends after the game the player’s name is gray and I can’t invite him.
and very often this inscription appear ( Disconnected . Game completed recorded! Restart Hearthstone to continue. )


All I need to do is “add friend” > click the last player played > (auto filled) > add


That’s exactly what i say but after i do this nothing happens even disconnects me


what device you playing on?
have you tried reinstalling the game?
