I'm stuck with this advanced query:

issue in linkedIssuesOfQuery('issue in parentsOfIssuesInQuery(\'Project = PROJECT_A AND Sprint = SprintXXXX\u002f10 AND TYPE = Story\')', 'implements')

There are some questions if nested queries can include functions, and it appears not.

Also, the Unicode character in the second nested query might be causing an issue, but I would need to test to be sure. You might need to escape the backslash, like \\u002f
