Thanks Sreeni for the reply.
I tired the tool. I can see the sitemap and it displays all the entities and the ares they belong to.
My issue is with all the related navigation links to Contact entities are visible but when I click on it, nothing happens. It does not take me to the related entity. Example: When I click on Audit History for a record in Contact, it stays on the record and
does not goes to related entity. This is only happening for Contact entity.
Any help would be greatly appreciated.
