In the dashboard, there is a section that tells you when the remote content items on your website, were last updated. We have improved this to add a tag that will tell you the reason for the remote content not synchronising, if there is an issue. You are then able to click on the profile from the dashboard, and then use the edit link on the profile, to update the source URL. You will then need to either force a synchronisation using the 'Actions' menu to 'Update remote content', or the profile will update when the next site wide remote profile synchronisation runs.
