"Can View" and "Cannot View"Related Lists are hiding on the "Announcement" form View.

ALL

There could be 2 reasons for this

1. Property glide.service_portal.user_criteria_enabled could have been set to false.
2. The announcement created would have the check box "Public" checked. 

If an announcement is not public, Then check for the value of glide.service_portal.user_criteria_enabled, It should be set to true.

If the Announcement is set to be Public, The "Can View" and "Cannot View" user criterias would not appear under the related lists. As those user criterias would not matter for a public record.
