iOS 7 has been released, and many of you Apple users may have upgraded your device or will be upgrading in the near future.
If you're already using library eBooks on your iPhone, iPad or iPod Touch, your Overdrive Media Console app will fail when trying to open a library eBook.
A fix is in the works, but in the meantime, the immediate remedy is re-authorize the app with your Adobe ID. If that doesn't work, the next step is to uninstall and re-install Overdrive Media Console app which will also require you to re-authorize with Adobe. IMPORTANT NOTE: A re-install will clear the bookshelf, history, and app settings from the app.
Your Bookshelf of checked-out eBooks will still be available from your eMedia Account so you can re-download any titles you still have checked out.
Refer to the iOS section of this Help article for assistance.
Any news about updates will be posted here.
I'm not sure what you mean by already using library eBooks, but mine seems to be working fine with iOS 7. My eBooks were expired (unrelated to iOS 7), so I simply checked them out again and it seems to be working fine.
That's great news! You're one of the lucky ones.
Overdrive expects to have a fix soon that will prevent others from having to uninstall/reinstall the app. In the meantime, you might want to take this opportunity to check out the new Overdrive Read format - no software required. Choose "Read in your browser."
UPDATE: Today (Tuesday, Sept 24) Overdrive announced that an app update for OverDrive Media Console for iOS users is now available in the Apple App Store. This new version addresses the issues that prevented users from opening eBooks in OMC for iOS v3.0.1 after upgrading to iOS 7.
After installing Overdrive Media Console v3.0.2, you may be prompted to re-authorize the app with your Adobe ID when attempting to open an EPUB eBook. If you've already re-authorized after installing iOS 7, you won't have to do it again.
