I've put a reference set selector in a dataview. For some strange reason, the buttons are not shown on the selector. The form is enabled The reference set selector is enabled The control bar is enabled Users have full rights on the object Additional information: microflow buttons are visible on the selector.
Are you sure the user has rights on the selection form? And if it is a new/delete button are you sure the user is allowed to create/delete the object?
Most issues around visibility are related to user rights.
