Jira Cloud is set up to report any status change, as can be seen in the above screenshot. For some reason, any change of status toward "Reviewing" or "Ready" are not notified, even though changes of status toward "In Progress" are. All other statuses work fine too, but they are not in the "In progress" Category, so I guess that's not really the same case.
What could trigger such a weird behavior and how can I fix it ?
