Group Libraries Not Appearing in Plug-In
I am a member of a private group, and I am unable to upload documents to the group using the plug-in. My own personal library appears in the plug-in but the group library does not. Is this an issue for the administrators of the group, or is there something wrong with how I have installed the plug-in?
1) You have Group Libraries collapsed: Click on the little triangle to the left of "Group Libraries" in the client
2) You haven't synced successfully since joining the group.
Do make sure you've checked 1), though. If it says "Group Libraries" on the bottom left of Zotero, that's very likely the problem.
