I found an open access article that isn't in Unpaywall.

"Great! If it's hosted by the publisher, we can almost certainly add it. If it's somewhere else, like a faculty page or a personal website, it may be trickier. These sites are difficult to include accurately since they don't provide their data in a structured way like institutional repositories do. Let us know at support@unpaywall.org and we'll see what we can do. "

Be sure to include the Primo permalink in your message when you report the error. It may also be helpful to provide the correct URL for the OA article.

Unpaywall Support responds quickly and the link is fixed within a few days.
