https://help.dropbox.com/view-edit/dropbox-ai-overview https://help.dropbox.com/view-edit/dropbox-ai-overview <- this page says the feature was only available on Dropbox Professional, Essentials, Business, Business Plus, and some customers on Dropbox Standard and Advanced. Basic free plans are listed. So while you may have had the toggle the actual feature, which is what you have to use to actually send data to OpenAI was not available therefore no data would be sent.
