You are most likely experiencing a connection issue. You can try the following steps to solve it:
- Make sure you have a stable internet connection.
- If you are connected to Wi-Fi, switch to mobile data and vice versa.
- Make sure you are still logged into your Google Play Store app.
- Check that purchasing has not been disabled in your Google Play Store settings.
If none of these work, make sure to contact our Support Team through the “Settings” menu in the game.
