Won't start while on data

T-mobile
Galaxy note 9
For almost 2 months I’ve been running into this problem where if I don’t connect to wifi, the game won’t start up, it just sits on the tavern doors. I’m a trucker driving on the open road, wifi is not free everywhere and often it’s unavailable. I have unlimited data, I used to play over data all the time. This problem started about 2 months back when the new engine was introduced.

you should check the technical support forum
