There are several options you can take to try and resolve this issue:
- Ensure that your mobile device satisfies the minimum requirements, which include having at least 4GB of available RAM. Devices with lower RAM capacities may experience unstable performance.
- Alternate between your Internet connections, switching from mobile data to Wi-Fi or vice versa.
- If you utilize VPN services, consider temporarily disabling them to check if your connection improves. Conversely, if you don't use VPN services, install and enable a VPN to determine if it enhances your connection.
- Ad providers may not have ads available, so you need to wait for them to appear.
Additionally, try to follow these steps:
1. Reboot your device.
2. Confirm that your BCW account is linked to your respective Google Play/Game Center account.
3. Uninstall the game.
4. Reinstall the game and your progress will be automatically restored.
