Apple released iOS 7 yesterday and many Apple users may have upgraded their device(s) or will be upgrading in the near future.
If you are an existing OverDrive Media Console (OMC) user who upgraded to iOS 7, the app will fail when trying to open a DRM-protected eBook. New or first time users of OMC are unaffected by this issue.
OverDrive suggests the following immediate remedies:
1) Re-authenticate the app with your existing or a new Adobe ID. Refer to the iOS section of this Help article for assistance. (Recommended)
2) Uninstall and re-install OMC which will also require you to re-authorize with Adobe. IMPORTANT NOTE: A re-install will clear your bookshelf, history, and app settings.
Audiobook users will not notice that anything is different unless you attempt to download parts of audiobooks you already downloaded to OMC before upgrading to iOS 7. You will receive an error message informing you to download the title again.
The issue has been noted and work is being done to remedy it as soon as possible.
If you have any questions, please do not hesitate to speak to a librarian at the 1st Floor Information Desk.
Sorry for the inconvenience.
