Getting a refund for an app purchase that didn't work out? If the refund is granted, don't expect support for any copies that remain installed. Until recently, App Store customers who received a refund for a particular app could still download updates and even reinstall the app
This is no longer the case, as Apple now prevents an Apple ID that has received a developer refund from receiving updates or redownloading the "returned" app. App Store refunds can easily be requested for a variety of reasons, ranging from accidental purchases to poor functionality. Once approved, the purchase price is returned to the payment method on file.
