An email is appearing in iOS users' inboxes informing them that if any of the microtransactions billed to their accounts "were unauthorized purchases by a minor" they should follow this link to apply for a refund.
"Apple is committed to providing parents and kids with a great experience on the App Store," the email said. "We review all app content before allowing it on our store, provide a wide range of age-appropriate content, and include parental controls in iOS to make it easy for parents to restrict or disable access to content.
"We’ve heard from some customers that it was too easy for their kids to make in-app purchases. As a result, we’ve improved controls for parents so they can better manage their children’s purchases, or restrict them entirely. Additionally, we are offering refunds in certain cases."
Requests must be submitted by April 15.
