She is playing Stardew Valley co-op multiplayer. She could not join a game hosted by her friend, I don’t think she tried to host one until after I put her computer on a profile without access control. I did try putting her DNS on Google, but that didn’t help, only turning off the access control worked. We can try some things if you have suggestions or need more information.
We haven’t tried Smash Bros since the update, we can try that for you, also.
