症状

In-App notifications are not received by Confluence from JIRA. The Applinks have been tested and it is possible to link to JIRA issues.

原因

JIRA is linked to more than one Confluence instance and the one that is not receiving notifications is not set as Primary.

ソリューション

• Log into the JIRA instance to which Confluence is linked

• Go to Administration>Application Links 

• Set the instance of Confluence for which you want notifications to Primary by clicking "set to Primary" next to the Applink
