Dear team,
How to find the JSM version
Regards
Karan
On Cloud systems, it is "Cloud".
You can extract a build number from the REST API if you try hard, but it's of no possible use to you - it's going to change every few weeks, and the number will tell you nothing about the application, let alone apps you might add. It's useless to you.
On server, help -> about will tell you.
You can only find version information if your JSM env is server (on-prems). In the cloud env, there is no version, it is controlled by Atlassian.
