App Store purchase now subscription
Hello, I purchased an app for 20.00 about 6 months ago from the App Store. The app developer now decided to update the app but change the pricing model to a 4.99 per month subscription. The app now requires me to subscribe to the 4.99 per month in order to use it—even though I previously already purchased the app before they decided to make it into per month subscription.
Can they do this? Am I entitled to a refund?
