we are having issues, where creator and assignee are not displaying the right usernames when we make changes to the username in the frontend. For ex: I create a user with username "x" Change the username to "y" Assign issues to "y" user Jira displays the issue as assigned to "x" and not "y" I know the app_user is not getting updated with the latest username, but if I manually make changes to the app_user table, will it impact other tables? will it still maintain the right reporter name in issues after i update the app_user table?
