This issue is known to occur if you have changed the clock on your device since installing the game. Please ensure the clock on your device is set correctly; this may fix your problem. If that does not work, please try fully closing your app, as this can fix this issue.
To fully close an app, follow these steps:
1 - Return to the iOS home screen 2 - Double tap the Home button on your device. A menu should slide open at the bottom of the screen 3 - Press and hold the CSR Racing icon in this bottom menu 4 - After a second, a minus sign should appear at the top corner of the app icon. 5 - Tap the minus sign to fully close the app.
If it does not solve your problem, I'm afraid there's nothing else we can do. The only solutions are to wait for the gas timer to count down to 0, which it will do eventually, or to pay 2 gold to refill your gas task, which often resets players' timers. To prevent this issue from happening again, please refrain from changing the clock unnecessarily in the future.
