Our organization is new in Jira/JSM world.
I am an Admin and I have two accounts in our organization, one as an Admin with Jira/Confluence and I am also a JSM Agent. It is all working fine.
I have another account and I am only JSM user, NO Jira license. I have Atlassian portal like the following. 
When I click the portal I use to see JSM button in it, I don't find it any more. Only the Confluence button is there.

Not sure what is changed that I don't find it. My assumption is, it is controlled by Atlassian but my org.
Please let me know if possible what I am missing and how to fix it.
Thanks
