Not sure where to post about this, I haven't used this in a few years.
I'm using an iPhone and I'm able to join people just fine, but when I host a game
(I make sure multiplayer is toggled on)
When I spawn in, and go to settings it shows multiplayer is off. I've checked my account settings and everything is either allowed, or turned on
I can join people's games just fine
Are you using a normal vanilla world with no add-ons?
Is your device using wifi or cellular data (or wired LAN)?
If not, what add-ons (name and creator), etc are you using?
