Deleting a collection from a group
I am relatively new to zotero and have not found a similar topic in the forum. My apologies if one does indeed exist. I belong to a group and have been adding references to the group via a collection. In my personal library on my desktop, I started another collection for that I eventually want to add to a different group. I accidentally added that new collection to the group on my desktop, which then synced online with the group. I deleted the collection from my desktop version. But that second collection is still visible to the group online. How do I remove the second collection and the references from the group in the online version?
