What is the recommended approach for Dave to change the base branch of a user story when he cannot see the Advanced button?

Changing the base branch of a user story is an important task that often requires specific permissions. When Dave cannot see the Advanced button, it indicates that he might not have the necessary permissions to modify the branch configuration for that user story.

The recommended approach for enabling this capability is to assign the Edit User Story Commit Base Branch custom permission to Dave. This permission specifically allows a user to change the base branch associated with a user story, thus providing the necessary access for modifications directly from the user interface. Without this permission, options to edit the base branch will be restricted, preventing him from proceeding with the change.

Other choices, such as switching to a different project or contacting support, do not address the underlying issue of missing permissions. While automatically inheriting permissions from other branches might seem helpful, it does not apply here because the root cause of the problem is specific to Dave's current permissions, not an inheritance issue. Thus, assigning the correct permission is the most effective and direct solution to enable him to manage the base branch effectively.
