Dunno if this is related, but something is still very wrong with searching on SFO-EWR route in Business for Flexible or Unrestricted fares. For example, if you search SFO-EWR on November 6 for Flexible or Unrestricted Business, it shows no such fares available on any flights that day. But if you search for Lowest available fare, it brings up fully refundable J fares on plenty of flights. If you search for J fares explicitly, they come up fine.
