A fellow colleague from my company complained that since the migration to cloud the KANBANBOARD related to his project stopped working, when trying to use already existent JQL filter (project =PDP and issuetype"Epic Link" = PDP-715 AND issueFunction not in hasSubtasks() OR project = PDP AND issueFunction in subtasksOf("'Epic Link' = 'PDP-715'") I get this error message "Error in the JQL Query: Expecting operator but got 'Epic Link'. The valid operators are '=', '!=', '<', '>', '<=', '>=', '~', '!~', 'IN', 'NOT IN', 'IS' and 'IS NOT'. (line 1, character 27).
I can't also switch to basic filter, could you please support w/ this?
