If after downloading specific downloadable content you still cannot access it in-game, or if the content is missing from “Your Add-ons,” please try restoring your PSN licenses from your PS4 Home Menu via the following instructions:

Select [Settings] > [Account Management] > [Restore Licenses]

After doing this, you can then check "Your Add-ons" again to see if this DLC is now available or check in-game to see whether it is available to use.

If the DLC is still not available to use, please make sure that your PS4 firmware is up to date and that you are using firmware version 6.71 or higher.

You can check your current firmware version by going to [Settings] > [System Information] on your PS4™ dashboard.
If this shows you are using a firmware version earlier than 6.71, please update your firmware by going to [System] > [System Software Update] on your PS4™ dashboard.
If you already downloaded the firmware, but have not yet installed it, you can do so under the Notifications section of your PS4™ dashboard.

After updating your firmware and restarting your console, please try accessing the DLC content again. If the DLC is still not available to use, you can deactivate and reactivate your PS4™ as your primary PS4™ console, which may allow you to access the DLC.

On your PS4™, sign into the account that you purchased or own the DLC content on.
From the PS4™ Home screen, go to [Settings] and select [Account Management].
Select [Activate as Your Primary PS4], then [Deactivate] then [Reactivate].
Once the process has completed, try accessing the DLC again in-game.
