If you have a Pinterest tab that is not fully up to date with all of your new pins and boards, there is an easy way to get everything in sync. Start by signing in to Facebook with an administrator account for the page. Then, at the bottom of the Pinterest tab, there is a blue link that says "Refresh Cache". Clicking this will automatically update all boards and pins on the tab.
This information also updates automatically, but it may take a while for your pins to appear. We run the updates periodically to ensure fast loading times for users and to reduce strain on the Pinterest servers. If you would like to update the tab at any time, just pressing "Refresh Cache" is the quickest way to do it.
