Rank hours haven't changed with the new site.
You are class 2 (Turboprop Captain) on the new site and should therefore be able to see class 1 and 2 flights.
In the map selector, it defaults to rank 1, there you would need to select the preferred rank from the dropdown (if available).
When you visit Dispatch -> timetable what options are there in the class dropdown? There should be Class 1 and 2 and when loading the page should be defaulted to class 2.
Also when visiting Careers -> Ranks You should see class 2 highlighted. Can you confirm to me please.
