If you made a purchase in our game and want it to be active on your other device, the instructions below will be helpful for you.
If your device runs on iOS, please make sure that you use the same Apple ID you used when making a purchase. Then go to Settings > Restore Purchases. Or you can try to make the ad-free purchase again. If this purchase is made earlier from this account, Apple will recognize the purchase and apply it for free.
For Android users, there is no such option at the moment :(
