I just purchased this game via my Steam account and the multiplayer simply does not work. Selecting the multiplayer button simply produces a message that indicates "You must log in to an Xbox Network account and have an active internet connection to play Grounded 2 online".
1. I do not care about Xbox, having an Xbox account, Cross Play, or having it linked to a Microsoft account. This is a steam game. Why don't you use the built-in architecture of Steam? It's not worth having to spend hours troubleshooting YOUR game to resolve critical issues with the game's base functionality that it claims to offer.
2. The product does not offer the services it advertises. Despite, the loophole of indicating "Early Access", you cannot bait and switch people into buying something that indicates it provides "online co-op with friends" when it doesn't since the feature is broken. This can be reported to Steam via the flag icon on the bottom right of the Steam store page.
I've seen multiple users reporting this same issue recently, so it is not just on my end.
