We've changed the sorting order of actions in the inbox page. Previously these were in order of the latest visit date. This has now changed so that those at the top are actions that have had a recent communication - this could be either you responding to a guest or the guest responding back to you. This was introduced at the request of clients who found it an easier way to see what needs attention. It is the latest in a series of changes designed to aid effective response management, such as improvements to contact status filters.
