After upgrading to jira 7.7.0 No issues are created
I get this error when I test the mail config
Found 2 unprocessed message(s) in the imaps folder.
Cannot create issue due to invalid license: [Sorry, you can't create any issues right now, as you need to have access to a JIRA application to be able to create issues. To gain application access you need to be a member of a group assigned to an application.]
