I am just starting to use and evaluate JIRA and I initially selected a trial of JIRA Service Desk Cloud. However, I really want to use only the standard JIRA Cloud service. I have configured several projects and would like to be able to use the standard JIRA issue types and avatars (e.g. Bug, Improvement, New Feature, etc) as see on this page: https://confluence.atlassian.com/jira/what-is-an-issue-270829373.html. However, the only issue types available are the Service Desk issues (e.g. Purchase, Incident, Problem, etc.). When I try to add a new type only the service desk avatars are available. Is there a way to revert an existing instance of Service Desk to the standard JIRA?
