The screen where you manage automatic download settings for subscriptions in the new iOS Newsstand is hard to find (at least it was for me!) Here is how to get to it on your iPad, iPod Touch, or iPhone.
- Tap on the Settings app to get to the Settings screen
- Scroll down list of settings until you see the icon for the Store and tap that
- There will be a section of the Store settings called "Automatically download new content when on Wi-Fi" and all of your Newsstand subscriptions should be listed there with an on/off slider for each one.
