CYW20721 is not a broad-market product. Can you please contact your local Cypress team or Cypress FAE? They will help you to get more support for your query.
This is Liam Lee working for Uniquest(Cypress Disty in KR) as FAE. I heard 20721 has changed to broad-market product. Also, Cypress recommended to use community rather than MyCase if possible.
Confirming that the 20721 is not broad market. Once the 20721 Product Manager agrees to engage on the opportunity (CY Sales and Regional Marketing in your region will need to reach out to him), he will line up the necessary internal resources for support and SFDC will be the tool you use to create tickets.
