Orders are usually delivered instantly but may take longer. When such delays occur, it means the purchase is still being processed. In some cases, payment processing can take up to 5 working days.
The process is fully automatic and the developers have no control over it.
You can also press the "Restore purchases" button in the game settings right now and after the expiration of the above period.
In case you haven't received your purchase in 5 days, you can contact us via chat in the right bottom corner.
You need to specify your in-game ID and attach your payment receipts from Google Play / App Store / App Gallery.
