From EA Solaire in that post:
Steam and the EA app:

• If you purchase DLC through Steam, you will not be able to transfer your DLC to the EA app- you will need to use the base game version in Steam.
• If your DLC is owned through the EA app, you should have access your DLC through Steam- you will need to own the base game through Steam and be sure your accounts are linked together.
