I can enter the game normally. Scout, practice members, choose songs, I can do all that. But the problem is that when I choose the song and it proceeds to load, the red note on the top freezes, and the whole game closes. The problem is it only happens when I connect to any portable hotspot, it works perfectly fine with wifi. Is it my device or what?
