Difference between Jira Work Management and Jira Software in under 10 minutes

[stefanholtker]

"When you got Jira Software that includes Jira Work Management" is not 100% true.
I ran into this issue with a Jira Software tenant, where i created a Work Management Project, wich had no AI Features.
The Support of Atlassian told me, that it only includes the Free tier features, in order to use AI in WM i need to get the Standard plan of WM too.
