Upgrade StorageBug Report: Undo Retrieve Metadata Missing
If you add a PDF to Zotero that contains the text "ISBN 978-3-406-83646-6", Zotero correctly retrieves the metadata. However, the button to undo the retrieval does not show up. (Tested on Windows with Zotero version 10.0.2 (64-bit) and on MacOS with Zotero version 10.0.1)
