It might also be possible to download the purchased content. It however depends on every publisher if they keep the option to enable downloads or if they decide to disable it.
A. Before the purchase
If the publisher enabled the publication for downloads, you will be able to see this before you purchase the publication. If you hover over DOWNLOAD, the message will reveal if the publication is or is not available for downloads.
B. After the purchase
Open the purchased content under READ - PURCHASES. The publication will open in full-screen. If the publisher enabled the publication for downloads, you will be able to see and click a download button (facing down arrow) in the top left corner of the screen.
Download the Content on Your App
By purchasing the publications, you get access to read the purchased publications on the Issuu app as well.
To read the purchased content in offline mode on your app you need to download it in the Issuu app itself. For in app downloads it doesn't matter if the publisher decided to disable the download option as it is not an actual downloading but rather an ability to save the publication.
1) Go to PURCHASES, open the particular publication and click on the download button (facing down arrow). A message will pop up saying, "Added to Downloads."
2) Go to your DOWNLOADS. When offline you can read the content here.
