Every single code on the opening page has been tested by multiple people as working for v1.1.0.
Good luck on GENNING Pokémon in PKHeX.
To be clear, for those naturally obtaining their Pokémon with their HA's you will not see any such illegal marks (if you were ever to check in PKHeX.) Next month when v1.2.0 comes out to support Pokémon Home, you will have access to even more HA's as many of the species without access to their HA's in Sword & Shield were from past games!
Next month, when you migrate your HA from your Pokémon Bank account on your 3DS, you will gain access to more species HA's for breeding (

This thread should be considered closed. We are a month-ish away from a new version of the game coming out and attention on the version 1.1.0 will be drawing to an end. If any ground breaking codes (ie. Instant KO's OR 100% Capture in Raids) are revealed, I will make an effort to update the opening page.
