Atlassian appear to have made a change to project roles which means that the We believe a recent change to Jira Cloud https://ecosystem.atlassian.net/browse/ACJIRA-1152 has impacted JEMHC's ability to update some issues and generate related notifications.
Historically, JEMHC gained required access to projects through the atlassian-addons-project-access which the JEMHCloud Add-On user is a member of has been removed from Jira projects. In turn, this has broken the generation of outbound notifications via JEMHC.Please ensure that your JEMHCloud Add-On user is a member of all issue security levels for the projects where JEMHC is used.access role, but as of 20th Dec appear no longer to be the case. The result of this is that JEMHC 'event' data is very limited, effectively stopping JEMHC having enough data to generate notifications from.
Workaround
If this impacts your instance, a workaround we have tested is to directly add the JEMHCloud user into each Issue Security Level.
