I tried it yesterday and the duo wasn’t working (no in-game boosts happening)
Can anyone confirm that it works now?
Make sure to check the stats in-game by going to substitutions and hitting Y or Triangle. Going to “Game Stats” and using the stick to view their actual card stats will not show the effect of the duo. As for their color-tier not showing or the dynamic duo symbol activating on the court, it’s very spotty — attribute that to a shit game. Hope this helps.
