If you launch the game and find it’s stuck on the loading screen, there are a few troubleshooting steps we suggest undertaking in order to get it to work:
1. We recommend reinstalling the game on your device.
2. Check your internet connection, as the issue may be caused by a connection problem between your network provider and the game servers. Sometimes switching between different types of internet connection could do the trick, you may also consider trying switching between Wi-Fi and cellular connection.
