Troubleshooting
No sound or music
Check that your device is not on silent mode and that the Music and SFX toggles in Settings are enabled. Voltline generates its own soundtrack — no external audio files are needed.
Purchase not showing
If your Full Game purchase isn't recognized, make sure you're signed in with the same Apple ID. Try restarting the app. If the issue persists, contact us at the email below.
Performance issues
