If you've purchased a bundle of Coins and they are not showing up in your inventory, it may be due to a slight server delay on our end.
Please check the App Store for any App updates that you may need to download and please close out and restart the app.
If your purchase still hasn't appeared, please go to Apple App Store Support to see your recent purchases and take a screen shot of your WR Studio purchase.
Please provide our Customer Service team with the screen shot by clicking on "Contact Us" in the "Help" section, and by clicking on the blue "+" sign in the bottom left corner.
