Your hearts should refill at a rate of one life every 30 minutes. If you notice they aren't refilling, try these troubleshooting steps on your mobile device:

• First, ensure your game is updated to the latest version by checking your device's app store. Keeping your game updated helps prevent many bugs.
• If no updates are available, close your game and any other apps running in the background.
• If your game is linked to an account, disconnect it within the game settings.
• Turn your device off, wait 10 seconds, then turn it back on.
• Relaunch the game and reconnect your social media account, double-checking that you're using the correct one.

If these steps don't resolve the issue, please try them a second time. If the problem persists, feel free to contact our support team for further assistance.
