Hi Jon, I was able to give everything a look. All looks good on the licensing side.
I'm thinking the issue is you're on an older version of the integration. Some things have changed on the Zendesk side which may have stopped this piece from working.
Try these steps:
Download the latest package for the integration here: https://www.sugaroutfitters.com/download/7921
Go to Sugar > Admin > Module Loader and install the new package. Do not uninstall the old package.
When the installation completes, go to Sugar > Admin > Zendesk Configuration and go through the steps again. Be sure to click on the "connect to zendesk" image even if it says you are already connected.
After following these steps, check to see if you're now seeing the information flow through.
Also, looking back over old emails you were looking for maybe some custom ways to search/match records. Did we get that setup for you? Our latest editions have the capability to do this, we just have to update your configuration to make it work that way.
To add the dashlet, you must be on a specific Contact record or Account record. The dashlet is available only on the record views. For example, click on the Contacts module, go to a specific contact record and see if you can add the dashlet on that page.
