ISBN lookups may often fail in the web library. We do our best to keep them working, but there's no dedicated metadata service for ISBNs (unlike for DOIs), and the main source often blocks requests. You will often get better results with the Zotero desktop app.
To look into this further, we would need to know the exact ISBNs for which the lookup failed.
