@n-triple-a Could you please see my comment and provide your feedback on the JIRA? Also, in an effort to promote clear communication and reduce duplicated effort, it is common to comment on the JIRA that you intend to work on the task before work begins, especially on JIRAs like this one which have had others already doing work on it and require a significant amount of work. Thanks! |
