Hello @johnnoarms,
your release has already been confirmed and delivered to the shops (so that they can perform their own quality checks before the release date).
If you want to replace the artwork, consider upgrading to our Amplify+ subscritpion, which allows you, among other perks like a 0% commission and advanced promotional features, to request a modification after the delivery.
You can either go for a monthly subscription or, if you prefer a better deal, for the yearly. We are currently offering a discounted price for the yearly susbcription. More info here
