Indeed.
Which Rule(s) do you believe are not being validated?
All Fare & Routing Rules options continue to function normally.
Fare Method: Not working for domestic fares. It also is not finding the lowest available fare.
Routing Rules: "The system was unable to locate a matching fare" for every fare I would describe as not working.
Validated as in ensuring departure date fits within effective window, duration is longer than minimum stay require yet shorter than maximum, and that the fare class of the fare basis is available on the given day and today's date would meet advance purchase requirements. Doing that is actually undesirable as it filters results.
