Suppose I am working for abc.com.
User with account user1.abc.com has created an instance xyz1.atlassian.com on Free plan of Jira Cloud.
Similarly, another user with account manager1.abc.com has created another instance xyz2.atlassian.com on Free plan of Jira Cloud.
How many such Jira Cloud instances on Free plan can be created by unique users in the same organization/domain abc.com? Is there a defined limitation?
