<p>Previously, customers could send you messages about orders via the "Comments and reviews" add-on. Since then, we have added a new add-on called "Message center". Unlike the old "Comments and reviews", the new "Message center" was designed for two-way communication. Administrators see the context of each message and receive notifications about new messages.</p><p>That's why we moved the order communication functionality along with your communication history from "Comments and reviews" to the "Message center" add-on. You don't need to do anything about it, but you can check where your messages are now. Like before, you can access order messages on the pages of individual orders, or in the <b>Customers → Message center</b> menu.</p><p><a href="[url]" target="_blank" class="btn btn-large btn-primary">View Message Center</a></p>
