New to JIRA Admin role (back up).
Started seeing outside users (not authorized or invited by our instance of JIRA) join our JIRA instance. Meaning, a user from an outside organization X that has their own JIRA instance is notified by our instance of JIRA Y on their request to get a license (in JIRA Y environment).
How do I address this issue so that outside users (JIRA X) are not directed to our (JIRA Y) instance? Thank you.
