Unfortunately, it is still not working for me. I am getting a new error “Sorry, but there was a problem importing items: There are no HTTP transports available which can complete the requested request.” I am working with this group library https://www.zotero.org/groups/books_to_be (147195). Everything is in folders nested within other folders. I put in an item not in any folder but received the same message. I receive this error when I click either import everything or import items.
