I didn't seem able to drop a full collection into a group library. Moreover, when dropping select individual files into the group library, some problems cropped up as well. I couldn't drop any individual links, snapshots and standalone notes. Any help would be welcome here.
The error report number which I got was: 57020805
I have the same problem with drag&dropping links, snapshots and notes (both standalone and linked to item). Is it supposed to be possible, or that not a feature yet? It would be very convenient.
I am also having the same problem. Somehow I got it to work at one point, but it only moved the citations and not any attachments or notes, although now I can't transfer anything including single files. Any ideas?
