Currently Views can only be edited/deleted by the Creator of the view: other operators can use, or save a copy to be edited, but not remove them.
If that Creator is unknown or no longer exists there is no way to remove that view if it is no longer needed, leading to clutter on the view list.
It would be beneficial for at least Operators with Admin level security have the ability to view/edit/remove views for all operators.
The idea has been reviewed by the Product Team, and may be considered for the roadmap. In the meantime it will remain in this status so other customers can vote and discuss the idea here. Votes and engagement around the ideas are data points the product team uses when prioritizing the product roadmap.
