Welcome me to your society of fallen hopes, guys!
I've already walked through the raising of a support request, as Renan advised.
And now I'm here - on the page of 3yo BUG with a minor severity...
I'm absolutely agree with Gavin's comment, which he wrote here in far 2017th - it's a "sucks".
The company I'm working for is never turn their back to clients as Atlassian does. (I've checked - we have only 426 bug tickets with Declined/Won't Do resolution of total 100.000+ bug tickets -> less that 4%).
And with this point of view they are dragging us into the annualy paid Datacenter edition with THE SAME policy of bug fixing. (off course everybody understand that this bug is still not fixed in DC for it's huge price)
Closing this bug as this is by design. Currently an agent license is required to use Organisation in JQL.
Please vote on the related Feature request https://jira.atlassian.com/browse/JSDSERVER-4873 if you would like this feature implemented.
