How to Delete an Audiobook From Your iOS/Android Device
If you need to delete a previously downloaded audiobook from your device (either to regain some storage space, to force an update or for troubleshooting purposes), follow these steps:
1. Swipe from right to left on the audiobook in the Audiobook List screen
2. Tap on the Delete button
The audiobook will now be deleted from your local device storage (don't worry! You can redownload it at any time you want in the future).
NOTE: Prior to version 1.7.0 If you are deleting the audiobook. We strongly recommend you then Force Quit the app and re-launch the app before trying to download the same audiobook again.
