Zinio only supports the latest version of their iOS Zinio App.
When going to the App store and trying to install the latest version, if the device is not compatible a pop up message will appear asking if you wish to download the latest compatible version. Please contact Apple or see their support article for further information. https://support.apple.com/en-us/HT201377
Apart from this exception Apple restrict developers from making old versions of their app available to customers, this means that unfortunately we can not send you a old version to download.
