I was able to play, but to be fair, I think it was having the Xbox host the game and the other devices connecting to it.

It started "failing" when I tried to switch it up, so that the Xbox had to connect to another device in the LAN, the local game is kind of there, but hidden, kind of annoying to be fair.

So in the end, this might not be as much of a bug I might have to tried to think it was, but really just an Xbox Live Gold rule which I think is not entirely reasonable as it's not going to use any outside resources that might need to be paid for maintenance.

Thank you for the response, GoldenHelmet.

Unfortunately, it's wildly inaccurate at least in my scenario, where no iPad is being used and the same behavior is observed.

Additionally I did manage to get it working after paying for an XBox Live Gold subscription.

This is definitely an issue where an XBox account without XBox Live Gold access cannot play LAN games, which is sad to say the least.

Hosting the world in the XBox is a viable option right now, Windows 10 can join the XBox LAN world.

I would like an update on this too.

Are you talking about connecting to each other on a local network? (same WiFi for example) 

Or online in different places each one of you?

I am also affected by this, I was normally able to play with my son on LAN, but this changed a short while ago.

The privacy settings have been changed to mostly nothing blocked, but nothing fixed this.
