I've tried everything I know to be able to play multiplayer grounded 2 on steam which I purchased day one and founders edition. I get this message every time I try to play multiplayer that's in the image attached. I don't know what to do to play the game with multiplayer. I have no issues playing the game on my pc on the xbox app what so ever it's only when I boot up the game through my steam account.... I REALLY NEED HELP!!!!!!!
