Autozone has reported an interruption in their integration to Protractor. They are working to resolve the issue, and we will update the status page when we have more information.
You may notice your catalog takes a long time to load and eventually displays an on screen error. If Autozone is in your top 3 suppliers, you can move them to position 4 or lower in Setup - Online ordering until the connection is restored.
Thank you for your patience. If you need assistance, please contact support.
