When logged in as admin user, yes, I see the hosts in Monitor → All Hosts. All users who have the Administrator role can see the hosts. It’s only when you remove the Administrator role from an account and leave only the ‘normal monitoring user’ role checked that this problem appears.
User Role configuration:
Relevant section from host detail view. The blacked out email address is the one associated with the ‘normal monitoring user’ account.
