I cant play with my friend

i cant play with my friend even tho we both have microsoft accounts, i have enabled the multiplayer mode but it doesnt show in the ingame settings, in the past we did play together, but now its impossible to play, and i dont know why, also we dont want to play under the same wifi, we both have enabled "use cellural data and wifi" and still doesnt work, im so furious about it, please let me know what to do.
