(FIX) (STEAM) "you must log in to an xbox network account..." every time you click multiplayer

[Blake Hodges]

I'VE FOUND A FIX THAT WORKED FOR ME

1. I made a new xbox account (had to make a fake email and everything).
2. Logged into that xbox account on the xbox app on my PC.
3. Profile > Settings > Link Steam. Linked my steam account to the new fake Xbox account.
4. Launched grounded 2 from my steam
5. Still didn't work initially. Enable crossplay > sign in to that new fake Xbox account > click multiplayer > fixed it
6. Quit grounded 2
7. Launch Xbox App > Sign out of fake new xbox account > sign in to your REAL Xbox account > Profile > Settings > Link your steam to your REAL Xbox account
8. Launched grounded 2 and it worked and is fully connected to my REAL xbox account and working

Could possibly just disconnect your steam from you xbox account through the app and then retry, but these were the steps I took.
