For the folks out there that enjoy audiobooks, but have had issues re-downloading ones you’ve purchased, it looks like Apple quietly implemented a fix.
According to a report published by MacRumors, following a support document recently discovered regarding downloading past purchases, Apple has made it possible to re-download past audiobook purchases through iCloud. For the people that have purchased those items directly from Apple, you can now restore those purchases on your iOS device through iTunes via iCloud.
Previously, the only way to find those old audiobooks would be to restore them from a backup saved on your computer. The support document states that the change was made on March 3, so it hasn’t been in the wild too long now.
On top of that, it has been discovered that iOS 9.3 users can have their downloads automatically delivered to their iOS devices as well, after a purchase has been made. You can find the settings in the Automatic Downloads section under Books & Audiobooks.
