We are also looking for a way to refresh oneboxes, in our case oneboxes of other topics in our forum.
Our use case is to build documentation across the forum, which may remix other wiki posts. But, since these are wiki posts, it’s obviously not ideal that the onebox won’t stay up to date with the many edits that are likely to be made over time.
It would be great if we could have a setting to automatically refresh oneboxes if they match the domain of our forum and/or belong to the category that this use case will occur in (wiki/docs).
