Unable to inline edit the 'Assignee' field in the Issue Edit/View screen

Question

For one particular JIRA project, I am unable to inline edit the 'Assignee' field in the Issue Edit/View screen, even though 'Assign to me' button appears on screen. I am Jira admin, I have checked and make sure that ALL Edit/View issue screen for all Issue Types in that affected Jira project has the "Assign' field. Workflow does not change/limit assignee permission.

What else did I miss?

Thanks.

Hello @Tony Yue ,

Good day! Welcome to Atlassian Community :)

Are you able to assign the issue by using "Assign to me" option?

Hi Tony,

What happens when you select the Assign to Me option? Is there an error? Is the field gray'd out? Something else? Are you able to assign to another person? Or no one shows up in the list?

Hello Enric,

Thank you very much for quickly providing suggestion to my question.
Yes, I, as a member of Jira support group, does have Edit and assign permissions. All users who have JIRA access can browse project.
That affected JIRA project utilized "Default permission scheme". This permission scheme is shared by 100 Jira projects, and only this one is having issue changing assignee, thus puzzling me.
