Please note that this problem is common when you don't have a stable internet connection. If you encounter this issue, please try the following:

1. Make sure you're connected to a network and that your connection is stable. Keep in mind that sometimes networks get overloaded or malfunction, meaning that the connection may not be stable regardless of what the indicator says. If you're having problems, contact your internet provider.
2. If you're using mobile internet, try switching to Wi-Fi. We recommend using Wi-Fi or a 3G/4G connection since they offer a better connection.
3. You can also try restarting your device and reloading the game.

If none of these steps helped, open another application to check your connection. If the problem persists, it likely has to do with your internet connection rather than the game.
