National Geographic put out an update to their app late last week and it is a terrible change. In the previous versions, you downloaded digital copies of the magazine and the format was really good. With the new update, all previously downloaded issues were deleted from your iPad and now the app is essentially a web-based browser that you use to view articles on-line only – you must now have an Internet connection to view issues. If you cancel your subscription, access to issues you have already purchased is lost, something that didn’t happen when you could download purchased issues. They’re getting hammered in App Store reviews and if you’re also an unhappy user, get in and leave a review and send them feedback at natgeomagazine@cdsfulfillment.com.
