Around two days ago a couple of fields are missing in all views. It seems to affect rather random fields. In one project it's "due date" and "assignee", in another project it's "Epic name".
I already checked the following:
- they all appear in the screen setup and in issue layout setup
- the screens are linked to the correct screen scheme
- the screen scheme is properly linked to the issue types in their projects
- and I made sure that everything applied to all kind of views
What am I missing and why did it work perfectly just a couple of days ago?
