1. To restore purchases of issues and subscriptions you've made within the app via the Apple purchase screens, simply tap on 'Restore purchases' or 'Missing issues'. -> This will ask you to login to your iTunes account. Then it will synchronise purchases you have made in the past and update your issues from 'Buy' to 'Download'. 2. To restore access to issues you are entitled to under a subscription you purchased or activated outside the app, simply 'Login' to your subscription within the app. The app will then synchronise with the subscription provider and will update each issue you are entitled to from 'Buy' to 'Download'
