Visiolink offers the automatic download feature for devices. This feature affects the download event in Google Analytics. With a regular download, the event is tracked when the user opens a publication and it starts to download. With the regular download, it is certain the user has actually opened the publication. With an automatic download, a user might have downloaded the publication without reading it. This causes a discrepancy between the applications with and without the automatic download feature.
The feature works differently depending on the device in use. These short descriptions will describe how the device handles downloads if the automatic download feature is enabled.
An automatic download on Android happens at 00.00, when the device checks if a new publication is available. If the device is unable to find a new publication, it will check again at 01.00. This will happen again up until 05.00, where the device will check for the last time. If no new publication is available at this time, the device will check again 00.00 on the next day. The automatic download will only happen if the device is connected to a wireless network or if the user has allowed download via 3G. The default setting is to only allow automatic download on wireless networks.
The automatic download on iOS is a kind of push notification the device receives when the publication has finished processing. When an iPad receives the notification, the application will start in the background and download the publication. However, the device cannot receive the notification unless it is on a wireless network. The device will therefore not receive the notification before a wireless network is accessed. If the device is charging overnight, it will periodically access the wireless network if it has the opportunity. In this case, the automatic download will trigger in the middle of the night. This will happen briefly after the processing is done.
There is a limitation with automatic download on iOS. It doesn't include pictures in Article View. The pictures are stored online and will be downloaded when the article is opened. This is usually not an issue, but is relevant if the user autodownloads a publication on wifi, but waits with opening the publication until the user is offline. This is unfortunate, but we are limited by a restriction made by Apple about how many times you can trigger a background download on iOS.
