Please, include more than just "Please fix this".

A few questions need to be answered:

• Are you logged into your Microsoft account?

• Is your friend logged into their Microsoft account?

• Is your console connected to the internet?

• Is your friend's console connected to the internet?

• Are you two friends in terms of Microsoft accounts?

• Is Multiplayer Game enabled in the world? (In the world list navigate to said world, then select the edit icon. Here, go to the Multiplayer option and check if Multiplayer Game is enabled or disabled.)

• You wrote you play on the same platform, same console. Are you in the same room with two controllers playing on the same Xbox One console? Or are you both playing from your homes and are trying to play over the Internet?

Answer all these questions and maybe include some extra information, that way, we might know more. (I'm not a mod, under we, I'm referring to the community and the mods as a whole.)
