A few users are unable to reorder Sub-tasks under its Parent issue view.
Platform Notice: Cloud Only - This article only applies to Atlassian products on the cloud platform.
Summary
Sub-tasks can be reordered within its Parent issue view by dragging and dropping the sub-task card.

The problem is that not all users with the same permission can reorder subtasks. Clicking on the subtask card does not allow reordering and only displays the issue information.

Environment
Jira Cloud (With Subtasks enabled)
Diagnosis
Reordering of Sub-tasks does not need any additional permission. Thus, this is not an issue with permission.
Cause
Sub-task list has a Filter to 'Hide done' sub-tasks from the view.
The reordering in the child issues panel will be disabled when the “Hide done” filter is enabled.
Solution
When you toggle the 'Hide Done' filter is on, it will remain persistent for all issues in that project.
The user who is unable to reorder sub-tasks will need to verify this and ensure to uncheck the 'Hide Done' filter to be able to reorder the sub-tasks.
