I PURCHASED THE PREMIUM ON IOS AND LATER GOT A NEW APPLE DEVICE. HOW DO I RESTORE PREMIUM?

For iOS users: ( scroll to next question for Android )

Try to use the button from settings menu inside the game. Your premium should be back.

If that doesn't work, log out of your Apple ID, then restart the iPhone/iPad, turn it back on and then sign back in with your apple id.

Launch the game and try to use restore button again.

Make also sure that in-app purchases are allowed on your device.

If that doesn't work, please see this Apple article with further instructions.
