I can't join servers with my cellular data.

I have set my settings to use cellular data since i don't have wifi. Even though i have done that, it still won't let me join the server i want to be in. It just keeps saying that i have to have wifi to play with friends. It has done this before, but i changed the settings to use cellular data and it was fixed. I had to update the game and now it won't let me join again even after i switched to cellular data in settings.
