I am trying to group by category in the list view in Jira. Which by my research is something that can be done. But category does not appear as an option for me to group by. Furthermore I am unable to find the category field when I go to add fields to the list view. When I go into the project settings under fields, Category does appear as well as when I open a ticket I am able to see category as a field in the issue itself. I am unsure of why this is not functioning correctly.
