Apple will allow some apps to automatically charge you higher subscription prices
 

Apple has announced an update to its subscription policy that's supposed to make auto-renews seamless but could also lead to surprise charges. Under the old policy, the tech giant will ask users to opt in before they're charged for a subscription that has recently raised its price. Going forward, however, it will allow developers to automatically charge higher prices, so long as they meet a set of conditions. Apple will notify users of the price increase in advance via email and push notification, but it's up to them to unsubscribe before they're charged.
