Steven ZahmYes, just add those to items to the cart. Then click the renew existing link and add copy/paste the license key into the field, then apply it. Do this for the other items to.
After you complete the purchase, navigate back to your WP admin. In a short while the updates will show available on the Plugins admin page. Click the Update Now link to apply the update. Be patient, it can take a some time to check our servers for the update. You can try navigating to the WordPress Updates admin page. This page checks for update more frequently than the Plugins admin page.
Hope this helps!
ps. Make you you have activated the license keys on the Connections : Settings admin page under the Licenses tab. They will need to be active in order for the update to be permitted.
