we should be able to use jira action node, but i have tried there are no Jira node even though jira already connected.we can only get only use jira node, in the journey from marketplace only, we cant use in any new journey.
i dont know whether it is bugs or i missed something during the integration.
@Abdullah_Zuhud For using jira integration action node in your journey, when you have to add a new node then you have to select integrations and then click on jira.
