WellSky pushed an update to the LSA export today, Wednesday, December 9 th at 12:00 PM Central. Please be sure you've re-exported and resubmitted to the HDX 2.0 after that date/time. This update resolved these specific flag ids: 484, 486, 538, 539, 757, 779, 780, 804 and 848.
Communities will spend the entire month of December working with their AHAR liaisons on data cleaning and vendors will continue to make periodic updates to the export to resolve flag files and incorporate new sample code. This will likely require several additional uploads to the HDX 2.0.
