I also played some arcade matches before HvV and GA today and didn't have the 'No data available' screen.
Played several matches of arcade today and then went into starfighter assault. This time everything worked as it should. No errors and got to see the end of round stats.
Maybe the other day was something else and this is finally fixed. First time since this bug started I have seen the stats screen without restarting the game.
It is not fixed. Had to leave matchmaking in GA this morning to see if i completed a timed challenge or not.
