Cool, happy to look into the example. Could you share one of the tables where that's the case? Also, are those profiles setup with the Job Changer signals?
One of things we could be encountering, since some of the data they collect comes from LinkedIn, if the profiles were made private (meaning you must be logged into the site to see it) then they may not be able to update some for that reason, because they don't use cookies or active sessions to pull data. However, we can check on a case by case basis to see if there are other reasons. Thanks!
