Unable for others to see my world while in multiplayer

So the problem is that in the latest Minecraft bedrock edition on Android, my friends can't see my multiplayer game that is to say they can't join my world, but I can join their worlds, realms, servers, etc without problem. I don't what's happening, also when I go to settings before creating the world I turn multiplayer on, but when I'm already inside the world and playing, and I go to settings, it shows that multiplayer is off!
And no, it's not my Xbox settings, because I checked them and multiplayer is available for me
