Version 2.0.2 of DEVONthink To Go which became available yesterday unveiled an issue that unfortunately didn’t surface even in our beta tests. In some situations it’s currently not possible to synchronize due to ‘pending files’. We have immediately sent a bug-fix release to Apple which is now waiting for Apple’s App Store review.
If you experience this problem also on the Mac you can create a custom smart group searching for Instance is Pending and Instance is not Indexed and remove or update the pending items manually.
We apologize for the inconveniences.
