A. 1. Check your internet connection: Ensure that you have a stable internet connection as rewards may not be issued if the game cannot connect to the server. 2. Restart the game: Close the app completely and reopen it to refresh the game state. 3. Clear the app cache: Go to your device's Settings > Apps > Tile Busters > Storage > Clear Cache. This can help resolve any temporary issues with the app. 4. Revisit the level: Sometimes, replaying the level can trigger the reward system to issue the rewards correctly.

B. 5. Update the game: Ensure that you are using the latest version of the game. Go to the Google Play Store, search for Tile Busters, and check for updates. 6. Check for device updates: Make sure your Android device is running the latest software version by going to Settings > System > System Update.
