I would like to give it a -6

This app was working perfectly a few weeks ago. But now whenever I want to play this game the app doesnt connect to my Wi-Fi even though I know theyre connected to the same Wi-Fi! Now what am I supposed to do, seems like a huge waste of money to get this game with the app does not cooperate. Somebody needs to fix this.
