Lindy Agent Not Updating Knowledgebases with New Docs and Web Pages Automatically

Hi All, I think I'm missing something simple but haven't found the right update to fix it. I have a Lindy agent that uses two knowledgebases: (1) a Google Drive folder that contains meeting minutes and (2) a newsletter/blog public website that contains weekly newsletters. When I set up the knowledgebase the agent pulls all of the articles and meeting notes from the initial sync, but does not add new docs or web pages to the knowledgebase as they are created (even after months). What am I missing here?
