"You must be connected to wifi to Play with your friends" While Playing using mobile data

This full release just released. And I found something wrong. I used to play with my mobile data and this is why I always keep "use cellular data" button on, but today when I updated the game it's showing an error. Whenever I tries to join any server like cubecraft, it says "You must be connected to wifi to Play with your friends". This is one of the worst problem coz I can't Play any server and with my friends. plz fix.
