Why can't I join my Xbox Minecraft World on my phone via Lan anymore when I did the same...

I am having the same problem, however, for me, it is my friend who is on the Xbox and I am on the Windows 10 version. He cant join the world that I created anymore. He can, however, join me if I create a new world and I can join any of his old
worlds. I Have a theory on what the problem is. We were playing the game fine one afternoon and we both had to get off for a bit to do other things. When I came back it said that my game was updated and some bugs were fixed. From then on my friend can't
join any previous worlds I created but he can join new ones. You will encounter a similar problem on the java edition of Minecraft if you try to connect to a server with a wrong client version. It appears as if the clients updated but the world it's self
did not which is why my friend can't join. That is my theory at least. I did what you said above and it and it still doesn't work.

Guys why i can't join in world of my friends on Minecraft?

Same here. The friends tab in Minecraft xbox changes the number underneath it as my LAN friends enter their world on their devices, so xbox is definitely recognising that they are there. I see that number change within seconds of them starting on their
device. But underneath that, it still says "your friends are not playing Minecraft right now" when they quite clearly are. My friends on other devices see each others joinable worlds, but I cant see those same worlds from my xbox. They can see my xbox worlds
and join, but i cannot see theirs. Help!

Make sure you are doing the following:

Multiplayer Options

Minecraft (Bedrock) supports the following multiplayer options:

• Locally hosted multiplayer world via LAN or Xbox Live
• Realms
• Servers (unofficial, third party server software)

Locally hosted multiplayer world via LAN or Xbox Live

Any world can be a locally hosted multiplayer world, and accessible to other
Minecraft players.

To start, create new world or load an existing one. Then, select World Settings (pencil icon) →
Multiplayer → Multiplayer Game. If all players are on the same local network, you may also toggle on
Visible to LAN Players.

Other player(s) can join the world by navigating to the Friends tab and selecting the world.
