Minecraft bedrock can't join friends?

As soon as I press join it says "Looking for server" and it continues. Have already done the standard things (restart, uninstall, reinstall, restart router) now the xbox support says that everything is fine with my network. My friends can also join me just not them. I can't join via LAN either 😔 Does anyone have any idea how to fix the bug?

Cross play or more info

So first of all awesome profile picture! 😂 and that is probably. The fact that you are not on the same internet or network.

Does your friend have a different version than you? If so, then one or both of you must update Minecraft
