Well this issue probably has been solved but I think my issue are probably new , i using cellular data to play Minecraft and I can joined realm and server but after I join the beta and I leave it cause I wanna play with my friend , I reinstall it to get back the public version , after I get back , I can't join a realm or server even though I turn on the " use cellular data " , every time I press join a realm or server it keep saying " you must connected to wi-fi to play with your friends" . Any solution for this issue ?
