DEVONthink To Go 2.1.1 just passed Apple’s review with important bug fixes. — For the new document provider extension feature to work, DEVONthink To Go 2.1 had to move the the database files to a new location shared between application and its extensions. On some devices this failed and resulted in an error message and an apparently empty database. Version 2.1.1 fixes this issue and makes the database accessible again. We apologize for the inconveniences.
In addition, DEVONthink 2.1.1 blocks the user interface less during heavy background operations like marking many thousands of documents as read or flagged.
We recommend this free update to all users. Update your copy through the App Store app or receive the update automatically, depending on your App Store settings.
