Sorry it was me who requested help from @ CawlinTeffid to split the topic.
I agree if you just need to set up 2-way sync it’s fairly straightforward.
It was a few weeks ago that I tested this plugin so I don’t have a good memory of it now. Could also be because of my other settings in Zotero. The plugin is indeed under very active development. I’m looking forward to Zotero 7 coming out of beta to give this plugin another try.
