Hey guys,
I had issues getting COD Modern Warefare 2019 to work on my PS4. I installed the game as well as the automatic update and kept getting missing DLC content and couldn’t find it on the PSN store. I found this YouTube video that worked for me.

Basically you need to sign up and log into Activision. Once I was signed in I could download all the DLC. You can’t find these on the PSN.
Hope it helps people in the future with this issue.
